Put the pork, 1 can of Coke and ¼ c. brown sugar in a Ziploc bag to marinade. Marinade for a few hours or overnight.

Pour meat and marinade into crock pot. Cook for 4 hours on high or 8 on low. Keep lid on to retain liquid.  Drain liquid. Shred meat with 2 forks when done.

Put shredded pork and Barbacoa Enchilada Sauce in crock pot and cook on low for 2 hours.

Note: The meat and the beans are both very saucy, which is nice if they are being served buffet style because it keeps them really moist, but be sure and use slotted spoons to serve them.
