Sweet Crockpot Baked Beans

6-8 slices of thick cut bacon
1 medium onion, diced
16 oz. package of small dried white beans (like navy beans)
1/2-1 cup dark brown sugar, firmly packed
1/4 cup molasses
1/4 cup cider vinegar
2 tsp. dry mustard
1 heaping tablespoon prepared dijon mustard
3/4 cup BBQ sauce (I like Sweet Baby Ray's Honey Chipotle)
5 cups water
1/2 tsp. salt
Start with your bacon.  Slice in half and fry over medium heat, just until fat is rendered.  You don't need to cook the pieces until they are brown and crisp.  Remove bacon from the grease and set aside.  DO NOT throw out the bacon grease.
Depending on how much grease your bacon gave, you may want to pour some off, but leave enough to cook your onions in until they are soft.
While your onions are cooking, mix together the packed brown sugar, molasses, cider vinegar, dry mustard, dijon mustard and barbeque sauce in a 5-6 quart crockpot/slowcooker.  Add the dried beans (no need to soak, but I do check for any rocks/debris that may have made it into the package), the cooked onions and the partially cooked bacon slices.
Add the 5 cups of water, stir all together.  Cook, covered on low for 12 hours until the beans are tender and the liquid is syrupy.
Before serving remove the bacon strips and discard, stir in 1/2 tsp salt and add pepper to taste.
Enjoy!
Note: For my non-onion eating friends, you could probably just leave those out...  :)
