Slow-Cooked Baked Beans with Bacon

Lightly coat a 3 1/2- or 4-quart slow cooker with cooking spray. Combine the beans, onion, celery, brown sugar, tomato juice, tomato sauce, ketchup, the 4 slices of chopped bacon, vinegar, garlic, dry mustard, and salt in the prepared cooker. Stir to combine.

Cover and cook on Low for 5 to 6 hours or on High for 2 1/2 to 3 hours. If desired, serve topped with sliced scallion and additional bacon.
