I have been making pulled pork this way for a long time. It is always a hit at parties. I cook Boston Butt Roast the day before, pull roast apart triming away the fat once cooled enough to touch and put in a crock pot the next day to heat up and keep warm for serving with a favorite BBQ sauce that I usually buy from a local BBQ restuarant in my hometown. Also, I like to serve on bakery hamburger buns if I can get them otherwise store bought ones are fine. Homemade coleslaw goes nicely with these sandwiches. It is good with slaw on top of the pork.
