Enchilada Casserole

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.
