Brown the ground beef and add the onion. Drain.
Add the beans, garlic, onion soup mix, water, ketchup, brown sugar, mustard, and vinegar to the cooked meat and onion.
Stir all the ingredients together and spread in a 9x13 in. dish.
Fry up some bacon, break it up into small pieces and sprinkle on top of the baked beans.
Cover the beans with aluminum foil. Bake at 375 F for 30 minutes, then uncovered for 15 minutes.
Here is the original recipe. I added my version below it.
