Put all ingredients in crock pot. Cook covered, until beans are done and meat falls apart easily; about 5-6 hours on high.
Shred pork and put on tortillas with cheddar cheese.
Note: Tapioca is a strange ingredient but it really helps the thickness of this pork. You need to buy the Quick-Cooking tapioca that may come in a little red 8 oz box. You would find this by the jello mixes. I would guess that you could use cornstarch or flour instead of tapioca but I haven’t done that before.
