For a healthy nacho casserole, use extra lean ground beef, low-fat cheese and light sour cream. To serve a larger family, double all of the ingredients and prepare the casserole in a 9 x 13-inch dish. The rest of the cooking instructions remain the same.
To assemble the casserole, spread 1/3 of the taco meat mixture (approx 1 cup) on the bottom of the casserole dish. Follow with 1/3 of the shredded cheese. Then place one of the low carb tortillas in the middle of the dish.
