Prepare the Chicken: Season the chicken breasts with fajita seasoning, ensuring they are evenly coated.
Cook the Veggies: In a large skillet, heat olive oil over medium heat. Add the sliced bell peppers and onions. Cook for about 5-7 minutes, until the vegetables are tender.
Assemble the Casserole: In a baking dish, layer the cooked bell peppers and onions. Place the seasoned chicken breasts on top of the vegetables.
Add Salsa: Pour the salsa over the chicken and vegetables, spreading it evenly.
Bake: Cover the baking dish with aluminum foil and bake for 25-30 minutes, or until the chicken is cooked through (internal temperature of 165°F or 74°C).
Add Cheese: Remove the foil and sprinkle the shredded cheddar cheese over the top of the chicken. Return to the oven and bake for an additional 5-10 minutes, until the cheese is melted and bubbly.
