Instructions

Season the chicken: In a large mixing bowl, combine 1 tablespoon fajita seasoning with 1 tablespoon olive oil and mix well. Add the sliced chicken breasts and stir thoroughly, using clean hands to ensure the chicken strips are completely coated with seasoning.
Prepare the casserole dish: Lightly grease a 9 x 13 inch casserole dish, then place the seasoned chicken evenly into the dish.
Season the vegetables: In the same mixing bowl, combine the remaining 1 tablespoon fajita seasoning and 1 tablespoon olive oil. Add the sliced bell peppers and onions, tossing them so each piece is well coated with seasoning and oil.
Add vegetables to dish: Spread the seasoned peppers and onions evenly over the chicken in the casserole dish.
Add cheese: Sprinkle 1 cup shredded cheese evenly over the top of the casserole.
Bake the casserole: Place the uncovered casserole in a preheated oven at 350°F (175°C) and bake for 30-35 minutes, or until the chicken is fully cooked and the cheese is melted and slightly golden.
Serve: Remove the casserole from the oven, top with fresh cilantro leaves, and serve hot accompanied by warmed small flour tortillas and your choice of optional toppings like sour cream, diced tomatoes, avocado, and sliced jalapenos.

Notes

Time Saving Tips: Pre-slice chicken, peppers, and onions ahead of time and store separately in the refrigerator.
Prepare toppings in advance by cutting and placing them in individual bowls, covered until serving.
Heat tortillas on a cast iron griddle five minutes before the casserole finishes baking for best flavor.
Serve directly from the casserole dish to minimize cleanup and keep the meal warm.
