Chicken fajitas offer a perfect balance of indulgence and nutrition. Packed with lean protein, fresh vegetables, and vibrant flavors, they make a quick and wholesome meal. This recipe uses low-carb tortillas and heart-healthy ingredients like avocado, making it a smart choice for anyone looking to enjoy a tasty dinner without extra calories. Plus, it’s easy to customize for picky eaters or busy families.
Why Choose Low Calorie Chicken Fajitas?
Chicken fajitas are naturally light when made with the right ingredients. Using lean chicken breast keeps the protein content high while minimizing fat. Fresh bell peppers and onions add fiber, vitamins, and antioxidants without many calories. Choosing low-carb tortillas helps reduce overall carbohydrate intake, which supports weight management and steady energy levels.
This meal is also quick to prepare, making it ideal for weeknights when time is limited. You can easily swap out ingredients to suit your family’s tastes. For example, if your kids don’t like peppers or tortillas, serve the chicken and veggies over rice or mix the chicken pieces into rice for a simple alternative.
Ingredients You’ll Need
1 lb chicken breast, cut into bite-sized cubes
1 pack Trader Joe’s Carb Savvy Tortillas (or your favorite low-carb tortillas)
3 bell peppers (red, yellow, or orange), sliced
1 yellow onion, sliced
1 lime
2 tbsp olive oil (divided)
1 ripe avocado or ½ cup guacamole
Salt & black pepper, to taste
Fajita Seasoning Mix
1 tsp chili powder
1 tsp paprika
½ tsp cumin
½ tsp garlic powder
½ tsp onion powder
½ tsp dried oregano
½ tsp salt
¼ tsp black pepper
Pinch of cayenne (optional)
Step-by-Step Cooking Instructions
Season the chicken
Toss the cubed chicken breast with the fajita seasoning mix until every piece is well coated. This blend brings smoky, spicy, and savory notes that make the dish flavorful without extra calories.
Cook the chicken
Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Add the chicken and cook until browned on all sides and fully cooked through, about 6-8 minutes. Remove the chicken from the pan and set aside.
Sauté the vegetables
In the same skillet, add the remaining tablespoon of olive oil. Add the sliced onions and bell peppers. Season with salt, pepper, and a sprinkle of garlic powder. Cook until the onions soften and the peppers are tender but still crisp, about 5-7 minutes. The vegetables will pick up the flavorful browned bits left from the chicken.
Warm the tortillas
Heat the low-carb tortillas briefly in a dry pan or microwave until soft and pliable.
Assemble the fajitas
Layer each tortilla with cooked chicken, sautéed peppers and onions, and slices of avocado or a dollop of guacamole. For extra flavor, add shredded cheese, salsa, or fresh cilantro if you like, but keep in mind these extras add calories.
Tips for Customizing Your Fajitas
For kids who dislike peppers or tortillas: Serve the chicken and veggies over steamed rice or mix the chicken pieces into rice for a simple, kid-friendly option.
Add more veggies: Try adding zucchini, mushrooms, or cherry tomatoes for extra nutrients and color.
Make it spicier: Increase the cayenne or add sliced jalapeños to the sautéed vegetables.
Use different proteins: Swap chicken for turkey breast or shrimp for variety while keeping the dish lean and healthy.
