    • Calories: 350
      • Carbs: 36g
      • Protein: 27g
      • Fat: 12g

What You’ll Need:

Chicken Seasonings:

  • 2 chicken breasts (12 oz total), boneless & skinless – thawed or frozen (I love working with frozen)
  • 1 tbsp olive oil
  • 2 tbsp lime juice (fresh is best, and the zest if you have an extra 30 seconds)
  • 2 tsp your favorite taco seasonings or make your own with:
    • 1/2 tsp chili powder (smoked and chipotle may add heat)
    • 1/2 tsp cumin
    • 1/2 tsp paprika (regular, smoked, chipotle, any kind you like)
    • 1/4 tsp garlic powder
    • 1/4 tsp onion powder
  • SECRET INGREDIENT: 1 Tbsp Soy Sauce. (Sub with 1/2 tsp salt, but it doesn’t have add the same depth of flavor.)
  • A pinch of pepper or fresh jalapeños to add a lil’ zing!

For the Veggies:

  • Bag of Frozen sliced peppers & onions or use fresh:
    • 3 big, juicy bell pepper or a small bag of sweet peppers (any color you love!), thinly sliced
    • 2 medium onions, thinly sliced
    • 1 tbsp olive oil (for sautéing)
    • 1 Tbsp Soy Sauce – Secret Ingredient- Just try it! Because this is the salt element of the dish, don’t add additional salt. Substitute with liquid or coconut aminos if you have it. You can use 1/2 tsp salt in place of the soy sauce but, it is the magic ingredient.

For Serving:

  • Your favorite corn tortillas (whole wheat or low-cal options are great to keep macros in check. For Picky Eaters: Use basic flour from a brand you love)
  • Fresh cilantro (because it’s the extra touch)
  • Lime wedges (for that zesty squeeze!)
  • Optional toppings: salsa, Greek yogurt (it’s like healthier sour cream!), or a bit of guacamole, my kids love shredded cheese and fresh pico de gallo and the husband loves with all the hot sauces on the planet.

Chicken Fajitas with Frozen Chicken

Let’s Make These Fajitas:

  1. Broil the Chicken:
    Frozen Chicken: Broil on High, on middle rack, for 5-10 minutes to help the chicken along. Meanwhile prepare Sliced Peppers, Sliced Onions and assemble seasoning ingredients. Thawed Chicken: Cut into strips and assemble on sheet pan.
    • Completely Optional Marinade Option if you have an extra few minutes. Rarely do I plan ahead enough to do this, but it does enhance the flavor. In a bowl, mix up your olive oil, lime juice, and taco seasoning or: chili powder, cumin, paprika, garlic powder, onion powder, soy sauce and optional pepper. Coat the chicken breasts in this flavor bomb and let them marinate for 15-20 minutes. (But hey, if you have an hour to spare, go ahead and let it marinate longer. The flavor gets even better!)
  2. Add the Veggies and Seasonings:
    Cut the chicken into strips, if you haven’t already. If using frozen chicken, it’s thawed enough now to cut through cleanly. In the same pan, add 1 tbsp of olive oil and toss in your bell peppers and onions. Sprinkle with seasonings, a pinch of pepper if you prefer, and the secret ingredient: soy sauce (if you haven’t marinated) and broil for 5-7 minutes until they’re soft, slightly charred in the best way, and totally irresistible. The chicken should be fully cooked (165°F or 75°C).
  3. Assemble the Fajitas
    Warm your tortillas in the pan for a few seconds on each side (don’t skip this step, it makes them so much better!). Then, load ‘em up with the chicken, sautéed veggies, and any toppings that make your heart sing—Greek yogurt, salsa, cilantro, and a squeeze of lime are all amazing options!
  4. Enjoy These Delicious and Healthy Chicken Fajitas!
    It’s so good, you’ll wonder why you haven’t made these sooner! 😋

Health benefits for Healthy Chicken Fajitas.

Each ingredient in this recipe brings something special to the table, from boosting protein intake to supporting heart health. Here’s a breakdown of the goodness behind each one:

1. Chicken Breast (Lean Protein) Health Benefits:
  • High in Protein: Chicken breast is a lean, high-quality source of protein, which is essential for building and repairing muscles, maintaining healthy skin, and supporting overall bodily functions. Protein also helps keep you fuller for longer, which can aid in weight management.
  • Low in Fat: Since chicken breast is low in fat, it’s a great option for those looking to maintain or lose weight without sacrificing protein intake.
  • Rich in B Vitamins: Chicken is a good source of several B vitamins, particularly niacin (B3), which plays a role in metabolism and maintaining healthy skin, and B6, which supports brain health and immune function.
2. Olive Oil (Healthy Fats) Health Benefits:
  • Heart Health: Olive oil is rich in monounsaturated fats, which are heart-healthy fats that can help reduce LDL (bad cholesterol) and lower the risk of heart disease.
  • Anti-Inflammatory: Olive oil contains antioxidants like oleocanthal, which has anti-inflammatory properties and may help reduce the risk of chronic diseases such as arthritis.
  • Rich in Vitamin E: Olive oil is a great source of vitamin E, which supports skin health and protects cells from oxidative stress.
3. Bell Peppers (Vitamins & Antioxidants) Health Benefits:
  • High in Vitamin C: Bell peppers are incredibly high in vitamin C, which boosts the immune system, promotes healthy skin, and helps with the absorption of iron from plant-based foods.
  • Antioxidant-Rich: The bright colors of bell peppers come from antioxidants like carotenoids (e.g., lutein and zeaxanthin), which support eye health and protect against cellular damage.
  • Low-Calorie, High-Fiber: Bell peppers are low in calories and high in fiber, which helps support digestion and keep you feeling full.
4. Onion (Nutrient-Rich & Flavorful) Health Benefits:
  • Anti-Inflammatory and Antioxidant: Onions contain sulfur compounds and antioxidants like quercetin, which help fight inflammation and reduce oxidative stress, supporting overall health.
  • Heart Health: The sulfur compounds in onions may also help lower blood pressure and improve cholesterol levels, contributing to heart health.
  • Rich in Fiber: Onions are a good source of fiber, particularly a type called inulin, which helps support gut health by promoting the growth of healthy bacteria.
5. Lime (Immune-Boosting & Refreshing) Health Benefits:
  • Vitamin C: Limes are an excellent source of vitamin C, which helps strengthen the immune system, reduce the risk of infections, and keep skin healthy.
  • Digestive Aid: Lime juice has natural acids that can help stimulate the digestive system, promoting better digestion and easing discomfort from bloating or indigestion.
  • Antioxidant Properties: Limes also contain flavonoids, which have antioxidant and anti-inflammatory effects.
6. Spices (Chili Powder, Cumin, Paprika, Garlic Powder, Onion Powder)
  • Chili Powder: Chili powder contains capsaicin, a compound that gives it its heat. Capsaicin has been shown to boost metabolism, support fat burning, and reduce appetite, making it great for weight management.
  • Cumin: Cumin is rich in iron, a mineral important for blood health, and has anti-inflammatory properties. It may also help with digestion and support healthy blood sugar levels.
  • Paprika: This spice is loaded with antioxidants like vitamin A and carotenoids, which support eye health and immune function.
  • Garlic Powder: Garlic has been used for centuries for its immune-boosting and heart-health benefits. It can lower blood pressure, reduce cholesterol, and support the immune system.
  • Onion Powder: Like fresh onions, onion powder offers anti-inflammatory and antioxidant benefits while contributing to flavor without extra calories or salt.
7. Greek Yogurt (Optional Topping) Health Benefits:
  • Protein-Packed: Greek yogurt is an excellent source of protein, which is important for muscle recovery and overall health. It’s especially beneficial for those looking to increase protein intake while keeping calories in check.
  • Probiotics: Greek yogurt contains live cultures (probiotics) that support gut health by promoting a healthy balance of bacteria in the digestive system. A healthy gut is essential for overall immune function, digestion, and even mental health.
  • Calcium-Rich: Greek yogurt is a good source of calcium, which supports bone health, muscle function, and nerve transmission.
8. Tortillas (Whole Wheat or Low-Calorie Options) Health Benefits:
  • Whole Grain Benefits (Whole Wheat Tortillas): If you opt for whole wheat tortillas, they’re a good source of fiber, which supports digestion, helps control blood sugar levels, and keeps you feeling full for longer.
  • Lower Glycemic Index (Low-Calorie Tortillas): If you choose a low-calorie tortilla, you can still enjoy the tortilla experience without spiking your blood sugar, making them a good option for those looking to manage weight or blood sugar.
9. Cilantro (Herb with Detox Benefits) Health Benefits:
  • Detoxifying Properties: Cilantro is thought to have detoxifying effects, as it may help remove heavy metals like mercury from the body.
  • Rich in Antioxidants: Cilantro contains antioxidants that support the body’s ability to fight oxidative stress and inflammation.
  • Promotes Digestive Health: Cilantro can help soothe digestive issues and improve gut health by supporting the function of the liver and digestive enzymes.

Overall Health Benefits:

  • Balanced Macros: This recipe provides a perfect balance of protein, healthy fats, and carbs—ideal for sustaining energy levels, building muscle, and supporting overall health.
  • Nutrient-Dense Ingredients: You’re getting plenty of vitamins (C, B6, A), minerals (iron, calcium), and antioxidants (from peppers, garlic, lime, and spices) in each bite.
  • Anti-Inflammatory: Many of the ingredients, such as garlic, onion, olive oil, and cumin, have anti-inflammatory properties that help reduce chronic inflammation in the body.
