1 pound ground beef
1 large onion, chopped
1 large green pepper, chopped, optional

In a Dutch oven, cook the beef, onions and green peppers over medium heat until meat is no longer pink; drain. Stir in the tomatoes, beans, tomato sauce and taco seasoning. Bring to a boil. Reduce heat; simmer, uncovered, for 30 minutes (mixture will be thin).
In a 13-in. x 9-in. baking dish, spoon in meat mixture. Top with chips and cheese.
Bake, uncovered, at 350° for 20-25 minutes or until golden brown.
