Heat the oven to 375 degrees. Spray a baking dish with nonstick cooking spray and set aside.

In a small skillet, heat the oil over medium heat. Add in the chicken, garlic, onion, and bell peppers. Cook until chicken is done and no longer pink.

In the baking dish, place one spoonful of enchilada sauce and spread around. Top this with a tortilla. Then spoon some of the chicken over the tortilla. Sprinkle with cheese.

Repeat the tortilla, sauce, chicken, and cheese layers until you get to the top tortilla. On top you’ll use sauce and cheese.

Place in the oven and bake until cheese is melted.

Serve warm with salsa, sour cream, and guacamole.
