In Dutch oven cook bacon, hamburger and onion until meats are browned and onion is tender. Drain off any excess fat (although you will want some.)
Stir in remaining ingredients.
Cover and bake at 350°F for 1 hour, or transfer to 4-quart Crock-Pot® and cook on low heat setting for 6 hours (or longer to cook off more of the juice...your choice.) 1 hour before serving (after 5 hours of cooking), taste beans, and adjust seasoning if necessary. Continue cooking for last hour.
