Soak the beans overnight, or for at least 2 hours in HOT water.
Brown the ground beef if necessary.
To the slow cooker, add the dried beans, browned ground beef, sloppy joe sauce, water and a little salt and pepper. Set on low and cook for 8 hours.
To serve, spoon the meat-bean sauce onto buns, and then enjoy the mess.
Freeze leftovers once they are cooled, in a plastic freezer bag or plastic container. To use, thaw in the fridge overnight, or place in a bowl of hot water. Then reheat in the microwave or stovetop.
Serve Slopp-Beany Joes with side salad or fresh fruit or veggies.
