This is a much-loved recipe from my mom. I'm not sure where she got it.

1 lb hamburger
1 onion, chopped
1 can whole corn, undrained
1 can navy or kidney beans
1 can pinto beans
1 15 oz can stewed tomatoes
8 oz tomato sauce
1 can Original Ro*Tel Diced Tomatoes & Green Chilies
1 package original dry ranch dressing mix
1 package taco seasoning

Brown onion with hamburger. Drain. Add rest of ingredients and simmer 15-20 minutes. Serve with corn chips, cheese, and sour cream.
