Rub the spices into the pork roast. Place the roast into a dish and let sit for 24 hours. Afterwards, pour the braising liquid in the dish and cover with two layers of tinfoil. Braise for 8-10 hours at 200°F degrees. Remove and shred meat; the meat should pull apart easily. Retain any braising liquid and reduce until it is a syrup consistency. Add the reduction to the pulled pork. Add green pepper and red pepper, cut julienne and sautéed.
Place four artisan buns on a cutting board. Apply cilantro lime mayo to each half. Add a generous portion of pulled pork. Top with mango ginger slaw and serve. Be sure to pile the pork and slaw high!
