Cut the bacon into 1-inch pieces. Add to a skillet and cook over medium-high heat until about ¾ done. Set aside.
Using a colander, drain the juices from the beans. Add to a 12-inch Dutch oven.
Stir in the chipotle peppers, to taste. Stir in the onion, mustard, brown sugar, BBQ and bacon. Adjust taste, if needed.
Cook over coals until the mixture reaches a boil, let simmer a few additional minutes and the mixture thickens just slightly. Serve warm with a slotted spoon.
Notes
If cooking in the house use an 11x13-inch casserole dish. Cook at 350 degrees F. for about 30 – 40 minutes.For a less intense heat, lessen the amount of chipotle peppers and adobo sauce.
