Start by cooking the hamburger and onion. Cook in a large pot on medium/high heat for around 5 minutes. Drain if you use the higher fat beef.
One can chili with beans, one can chili without beans and finally one can of chili beans. Add one can tomato soup, then one can water (using tomato soup can), one can diced tomatoes and one can drained northern beans.
Return the meat to the same pot.
Put a lid on it and let simmer for 10 minutes. Serve with sharp cheddar cheese and crackers. Enjoy!
