2 large boneless skinless chicken breasts cut in half lengthwise to yield 4 pieces of chicken
4 tablespoons oil divided
1 teaspoon chili powder
1/2 teaspoon ground cumin
1/2 teaspoon garlic powder
1/4 teaspoon cayenne pepper
1/2 teaspoon onion powder
salt and pepper, to taste
8 fajita-size (6 or 8 inch) flour tortillas
3-4 bell peppers, thinly sliced any combination of green, red, yellow, and orange peppers
1/2 onion, thinly sliced
mashed avocado see note
Whisk together salt, pepper, chili powder, cumin, garlic powder, onion powder, and cayenne pepper. Drizzle 2 tablespoons oil over the chicken and season with the spice mixture, then rub into the chicken on both sides with your fingertips.
In a medium bowl combine sliced bell peppers and onions. Drizzle with oil, then season with salt and pepper to taste.
Preheat oven to 400 degrees. Arrange seasoned chicken and peppers/onions on a large sheet pan. Bake for 20-25 minutes until chicken is fully cooked through. Allow to cool slightly before slicing chicken into thin strips. Serve with tortillas and toppings OR proceed with meal prep option.
Preheat grill to medium heat. Place chicken on grill, turn after 6-8 minutes and continue to grill until cooked through. While chicken is grilling, place a large piece of cooking foil on the grates where the chicken is not cooking. Transfer peppers and onions to the foil and toss occasionally with a fork or tongs to cook evenly until tender and edges just begin to char. Allow to cool slightly before slicing chicken into thin strips. Serve with tortillas and toppings OR proceed with meal prep option.
Stovetop / Skillet Method
Cook chicken and veggies in a large skillet over medium-high heat for 15-20 minutes, turning chicken and tossing veggies occasionally to ensure even cooking. Allow to cool slightly before slicing chicken into thin strips. Serve with tortillas and toppings OR proceed with meal prep option.
Meal Prep Option
To keep your toppings fresh, place them in small condiment containers. For the tortillas, heat for 15 seconds in the microwave, then fold and place in sandwich-size ziploc bags, two tortillas per bag. Arrange tortillas, toppings, and cooked chicken and veggies (cooled to almost room temperature) in meal prep containers, top with lid, and chill until ready to use.
To reheat (optional), simply remove the condiments and tortillas and heat the chicken and veggies in the microwave for 1-2 minutes, then assemble fajitas as desired.
