2 lbs hamburger, seasoned for tacos
1 onion, chopped
25 oz jar garlic/tomato pasta sauce (or tomato sauce)
1 cup water
1 can olives, sliced
4 cups grated cheddar cheese
12-14 corn tortillas
Cook together hamburger, seasoning, and onion, then add pasta sauce, water, and olives and simmer. Spread some of the meat mixture in the bottom of a large casserole dish, then layer torn tortillas, meat mixture, and cheese. Repeat until ingredients are used up, ending with a layer of cheese. Cover and bake at 325˚ for 30-40 minutes, then remove lid and broil for 5 minutes or so until cheese is crispy and browning.
