In a stove top pan, on medium high heat saute the chopped onion in vegetable oil until translucent. Season with salt and pepper to taste.
Add the ground beef and cook until no pink remains. Drain any excess fat from the pan.
Stir in the ketchup, brown sugar, Worcestershire sauce, mustard, vinegar, soup and seasonings. Taste and adjust the salt and pepper to taste.
Allow the chili to simmer on low heat for 30 minutes, then serve or freeze.
a) For a timesaver, make a large batch and freeze it in separate portions for future meals. b) You may substitute beef broth in place of french onion soup, and tomato sauce or Heinz chili sauce in the same amount in place of ketchup, if desired.
