How to Make Easy Queso Smothered Fajita Casserole

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Cook the Fajita Filling: In a large skillet, heat olive oil over medium-high heat. Add the sliced chicken or beef and cook until browned. Add the bell peppers, onion, fajita seasoning, garlic powder, smoked paprika, salt, and pepper. Sauté until the vegetables are tender and the meat is cooked through. Set aside.
