Cook meat until done. Drain, if necessary. Set aside.

Saute onions in butter, add the garlic, salt, tomato sauce, vinegar, chili powder, and cover and simmer 15 minutes. Mix in beans. Grease or spray a baking dish, cover bottom with 1/3 chips, 1/3 cheese, and half the meat sauce. Add another layer of 1/3 chips and cheese, and rest of meat sauce. Top with remaining chips and cheese. Bake, uncovered, at 375 degrees for about 20 minutes until hot and bubbly.

Mix onions and lettuce together, arrange equal amounts on plates, spoon casserole over top. Garnish with sour cream or yogurt and an olive on each serving. Makes 6 to 8 servings.
