This was so easy I can't believe someone had to suggest it to me...I should have thought of this on my own!
Place a couple of pork roasts in the crockpot and add about 3/4 bottle of your favorite barbecue sauce. Add a dash of worchestershire sauce and then pepper to taste. Slow cook it for about 5-6 hours until it is really tender, then use kitchen scissors (stick them right in the crockpot) and snip it to bits.
Put the meat on a crusty roll and voila!!...yummy easy lunch...with enough for leftovers. Gotta love crockpots!
