Brown ground beef in a large dutch oven and drain. Add the Enchilada sauce, soup, milk and green chilies. Heat until bubbly. Add the crushed Doritos and a few shakes of hot sauce if desired. Stir well.
Pour into 9”x 13” pan (Sprayed with a little oil helps with serving & clean up). Top with American cheese slices (don't crowd).
Bake at 350 degrees for 20 minutes, or until bubbly. Cool for about 20 minutes before cutting.
