Enchilada Pie - cooking recipe

Ingredients

3 lbs ground beef
3 onions, chopped
3 teaspoons salt
1 teaspoon pepper
3 tablespoons chili powder
24 ounces tomato sauce
18 corn tortillas, spread with butter (I spray with a little cooking spray)
12 ounces black olives, drained and chopped (I use 3 cans sliced olives, drained)
3 cups sharp cheddar cheese, shredded
1 1/2 cups water

Preparation

Brown ground beef and onion; add seasonings and tomato sauce.
In 3 2-quart casserole dishes (I use 3 square foil pans for freezing), alternate layers of tortillas (can be cut into 1-inch pieces), meat sauce, olives and cheese.
Add 1/2 c water to each casserole. Cover tightly. Label and freeze. Thaw casserole completely.
Bake at 400 degrees for 20 minutes.
