My family LOVES this recipe.. which is easy and cooks in the crockpot all day! The sauce it makes is fabulous. When the meat is done, shred it and eat over rice with the "sauce"... or make into a sandwich with crusty rolls.
Mix Marinade ingredients together and marinate roast in refrigerator for 4 hours minimum to overnight.
Put roast, all marinade ingredients, plus onion slices, garlic and bell pepper into your crockpot or slow cooker.
Cook on low for 8-9 hours.
When roast is close to being done, make black beans: Rinse and drain canned beans. Mash them with a fork and add chopped onion, cumin and 2 T of sauce from the crockpot. Mix all together and heat on low until warm.
Remove from crockpot. Shred meat. Serve over cooked white rice and black beans, with some of the "sauce" from the pot over the meat.
