This is a variation on King Ranch Chicken. This is not my favorite recipe, but Nathan LOVES it. He loves the super saucy chicken and of course he loves Doritos. I haven't made this for probably 9-10 months, I forgot I even had this recipe.
4 chicken breasts, cooked and shredded
2 cans cream of chicken soup
1 can Rotel brand tomatoes
2 cups cheddar cheese
nacho cheese Doritos
Crush Doritos into large pieces and layer them into the bottom of a 9x13" casserole pan. In a bowl mix soup, Rotel, and chicken. Spread the chicken mixture over the Doritos. Top casserole with cheddar cheese. Bake at 350 for 25-30 minutes, or until the cheese is nice and melted.
*I've used the cream of chicken soup, Rotel, and shredded chicken as filling for enchiladas before, that and some cheese. It turned out really nice.
