Chop the onion.

Sauté the chopped onion with the hamburger meat in a pot.

Drain the grease from the cooked meat.

Add the drained kidney beans, cooked hamburger meat and onions, and Ro-Tel tomatoes into the pot.

Bring the mixture to a boil.

Reduce heat to low, cover the pot, and let it simmer for 30 to 45 minutes.

If more juice is desired, add water to reach the desired consistency.

Serve hot with cornbread, crackers, or Cheddar cheese.
