Smoky, sweet, salty barbecued beans basically cook themselves when you throw everything in the slow-cooker.

Cook the bacon and onion in a skillet set over medium heat, stirring occasionally, until bacon is crisp and onions are tender.
In a slow cooker, mix the bacon, onion, and remaining ingredients, including the reserved bean liquid. Cover and cook on low heat for 3-4 hours.
