Instructions
Step 1

Gather ingredients and equipment. (Cutting Board, Measuring Spoons, sharp kitchen knife, sheet pan/baking dish, spritz of non-stick *remember, you are using oil drizzle so not too much*.)
Step 2

Preheat the oven to 400°F. Mix all of the spices for the fajita seasoning in a small bowl and set aside (chili powder, paprika, onion powder, garlic powder, cumin, cayenne pepper, sugar, and salt).
Step 3

Cut the onion and bell peppers into 1/4- inch wide strips. Slice the chicken breast into thin strips. Add the chicken and vegetables to a large baking sheet or casserole dish.
Step 4

Drizzle the cooking oil over the chicken and vegetables, then sprinkle the fajita seasoning mix over top. Use your hands to toss the ingredients until everything is well coated in oil and seasoning. Spread the chicken and vegetables out over the baking sheet evenly.
Step 5

Bake the chicken and vegetables in the preheated oven for 35-40 minutes, stirring once halfway through. Squeeze the juice from half of the lime over top of the meat and vegetables after they come out of the oven.
Step 6

To serve, scoop a small amount of meat and vegetables into the center of each tortilla. Top with a few sprigs of cilantro, a dollop of sour cream, and an extra squeeze of lime if desired.
