Step 1

Preheat oven to 425 degrees. Line a large baking sheet with tin foil and place it in the oven while you prep the vegetables and chicken.

Step 2

Pound the chicken breasts with a meat mallet until they are of even thickness. Coat the chicken with 1 tablespoon of olive oil. Mix the spices together in a small bowl and then sprinkle over the chicken in an even layer (both sides). Slice the chicken into long strips, about 1 - 1/2 inches wide.

Step 3

Toss the bell pepper slices and onions with the other tablespoon of olive oil. Remove the hot sheet pan from the oven and spread the peppers and onions in an even layer. Place the chicken strips among the vegetables.

Step 4

Place pan back in the oven and cook for 20-25 minutes, or until the chicken is cooked through.

Step 5

Serve with warm tortillas.
