1 pound ground beef, extra lean

1/2 cup onion -- chopped

1/2 cup green bell pepper -- chopped

1/4 cup water

8 ounces tomato sauce

6 ounces tomato paste

1/2 package taco seasoning mix

1/2 cup black olives -- chopped

6 flour tortillas non-fat

1 cup mozzarella cheese non-fat -- shredded

1 cup cheddar cheese non-fat -- shredded

Preheat oven to 375 degrees F.

Cook ground beef with onions and green peppers. Then combine the drained beef with the tomato paste, sauce, water and seasoning and simmer until thick and bubbly. In a 13 x 8 pan make a single layer with 3 of the tortillas. Pour half of the sauce over it evenly, and sprinkle half the olives and half of the cheeses. Repeat. Bake for 25 to 35 minutes.
