I'm linking to the recipe on Gluten-free Goddess. My only changes were doubling the recipe, using a much cheaper, pot roast type cut of meat like chuck roast, and cooking for 10 hours on low since I didn't cut the meat into serving pieces or brown it. If I made it again, I'd probably half the amount of balsamic vinegar used.
