Cover with lid and cook on low for 8 hours until meat falls apart
Shred meat in slow cooker with meat masher or a fork
Preheat oven to 350
Once you have meat shredded, you will take a 9X13 oven safe dish and spray with nonstick spray
Add bottoms of the buns down on the dish and add light mayonnaise over them
Then with a tong add meat over the top of all the buns then slices of provolone cheese covering the surface of all the meat. These will overlap and that is ok.
