1. Put bacon grease in the bottom of a large oven proof pot with lid. Put onions and garlic in next. Add meat and then remaining ingredients. Cover with water 1/2 inch over the top of the meat.
  2. Bring to a boil over high heat and reduce to medium high. Continue cooking, uncovered, until most of the water is cooked out, about 1 1/2 hours.
  3. Cover the pot and place it in a 450º oven and cook for about 30 minutes or until browned and tender. Check on it every few minutes to make sure it does not burn. Remove the bay leaves.
  4. Shred the meat with a fork and serve with tortillas and desired toppings.
