Instructions

Season the Chicken: Place one tablespoon of fajita seasoning and one tablespoon of olive oil in a large mixing bowl. Mix well, then add chicken strips. Stir and use your hands to ensure the chicken is fully coated with the seasoning.
Prepare the Casserole Dish: Grease a 9 x 13 inch casserole dish, then place the seasoned chicken strips evenly inside.
Season the Vegetables: In the same mixing bowl, combine the remaining one tablespoon of fajita seasoning with one tablespoon of olive oil. Add the sliced bell peppers and onion strips, and toss well to coat them evenly.
Add Vegetables to Casserole: Spread the seasoned peppers and onions over the chicken in the casserole dish.
Add Cheese: Sprinkle the shredded cheese evenly over the top of the casserole.
Bake the Casserole: Place the dish uncovered in a preheated oven at 350°F (175°C). Bake for 30-35 minutes until the chicken is fully cooked and the cheese is melted and bubbly.
Serve: Remove from oven, garnish with fresh cilantro leaves. Serve hot with warmed flour tortillas and your choice of sour cream, diced tomatoes, avocado, and sliced jalapenos.

Notes

Pre-slice the chicken, peppers, and onions ahead of time and store separately in the fridge to save time.
Prepare all toppings in individual bowls ahead of time and cover until ready to serve.
Heat tortillas on a cast iron griddle about five minutes before the casserole finishes baking for best flavor and texture.
Serve the casserole directly from the baking dish to minimize cleanup.
