In a 13x9 pan pour meat mixture in. Crush bag of chips and add to meat. Pour about 1/4 cup of water to mixture to add moisture. Mix together and spread out in pan as you would a cake mix. Place cheese on top, spreading evenly.
Put in to oven and bake until cheese is melted. If you desire you may add chopped lettuce and diced tomatoes on top to make a taco like casserole.
