Creating Chicken Fajita Casserole is a breeze with these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Sauté Vegetables: In a large skillet, heat a tablespoon of olive oil over medium-high heat. Add the sliced bell peppers and onion. Sauté until softened, about 5 minutes.
3. Combine Chicken and Beans: In a large bowl, combine the cooked chicken, corn, black beans, fajita seasoning, and salsa. Mix thoroughly.
4. Add Vegetables: Stir the sautéed bell peppers and onions into the chicken mixture.
5. Layer the Dish: In a 9×13-inch baking dish, layer half of the tortilla strips on the bottom. Spread half of the chicken mixture on top, followed by half of the cheese.
6. Repeat Layering: Repeat this layering process with the remaining tortillas, chicken mixture, and cheese.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes or until the cheese is bubbly and golden.
8. Garnish: Remove from the oven and let it cool for a few minutes. Optional: garnish with fresh cilantro before serving.
