A friend of mine recently had a dinner party for 20 people. She made pork in the slow cooker. Then as sides made chalupas, beans, rice, and a couple of homemade salsas. She described her recipe for the pork and it sounded delicious and easy -- She out a few ladels of tomatillo sauce in a slow cooker. Rubbed fajita seasoning on the pork (Boston butt). Put that in the slow cooker with another ladel of tomatillo sauce on the pork. Cook that overnight. Put the cooked pork in the fridge so it cooks and the fat congeals a bit. Remove whatever fat you can from the pork and pull it apart with forks or whatever. Then she reduced the sauce that was in the slow cooker (tomatillo and pork juices) and poured that on the cooked pork.
