Place the freeze dried pork into a bowl. Pour 3 cups of water over the pork. Let the pork hydrate for 10 minutes or until soft. Once the pork is soft, drain the water completely. Microwave the pork for 5 minutes or until warm. To the pork add the bbq sauce and chipotle peppers. Stir slightly to toss the pork in the bbq sauce.
For the coleslaw, slice the cabbage into thin strips. Place the freeze dried pineapple chunks into a bowl and add a little water to hydrate. Add the slices of carrots, green onions and cilantro to the cabbage. Add the mayo, Sriracha, mustard, salt & pepper. Toss until the cabbage is coated. Add the hydrated pineapples and toss.
Slice the roll open in half and place a generous portion of pork on the roll and top with the coleslaw.
