Stir the picante sauce, cranberry sauce, sugar, mustard and nutmeg in a 6-quart saucepot. Heat to a boil over medium-high heat and cook for 10 minutes. Add the pork to the saucepot and heat to a boil. Reduce the heat to low. Cover and cook for 2 hours or until the pork is fork-tender.
Remove the pork from the sauce and cool slightly. Shred the pork, using two forks. Return the pork to the sauce and heat through. Serve about 1/2 cup shredded pork in each roll. Top with lettuce and coleslaw.
