Brown your hamburger, after its browned, mix in your taco seasoning and sauce. Mix it up. Then crush your chips and put a layer of chips on the bottom of your 9×13 or a smaller square dish. Spread a little bit of your hamburger mixture on top.. Take some sour cream and spread it over the hamburger. It doesn’t have to be perfect. Add cheese, then chips. Repeat mixture till you reach the top. Cover with cheese and bake at 350 till the cheese is bubbly.
