How to Make Easy Mexican Chicken Casserole

Preheat Oven: Begin by heating your oven to 375°F-this ensures the casserole will cook evenly and thoroughly.
Cook Chicken: In a nonstick skillet, warm olive oil over medium heat. Sauté diced chicken with taco seasoning for about 2-3 minutes, until the chicken is golden and coated in flavor.
Prepare Vegetables: While the chicken is cooking, dice your bell peppers and set aside. Don't forget to drain and rinse the black beans and tomatoes for a clean flavor!
Combine Ingredients: Add the diced bell peppers to the skillet, cooking an additional 2-3 minutes until they're slightly tender. Stir in the salsa and let it cook for 2 minutes before mixing in cream cheese until it melts and blends smoothly.
Layer Casserole: In a baking dish, start by placing one-third of the chicken mixture at the bottom. Cover with two tortillas, then add half of the remaining chicken and half a cup of cheese. Repeat the layering process and finish with the last tortilla, topped with the remaining chicken mixture and cheese.
Bake: Cover your casserole with foil and place it in the oven for 20 minutes. Once that's done, remove the foil and let it bake for another 10-15 minutes until the cheese is melted and bubbling beautifully.
Serve: Once it's out of the oven, enjoy your Easy Mexican Chicken Casserole immediately, pairing it with condiments like Cholula or green Tabasco for an extra kick!

Optional: Garnish with fresh cilantro or avocado slices for an extra touch of flavor.
