1 pkg. Cooler Ranch Doritos chips
2 cans chili
2 can cream of mushroom soup
Preheat oven to 350 F. Crush Doritos chips into bottom on 13x9-inch baking dish. Mix chili and cream of mushroom soup together; pour over Doritos. Cover with cheese. Bake until cheese is melted and inside is warm, approximately 15-20 minutes.
Note: The leftovers of this casserole really aren't that great because the chips get soggy if they sit for very long. If you want to make this up but plan to have leftovers, combine the chili and mushroom soup and put into a casserole dish. Cover with cheese and bake until warm and the cheese is melted and bubbly. Then put a single serving of crushed Doritos chips on a plate and cover with the chili mixture. This way you can add fresh Doritos chips to every serving and don't have to worry about soggy chips.
