In a medium bowl, whisk together the mustard, honey, brown sugar, apple cider vinegar, ketchup, Worcestershire sauce, garlic powder, onion powder, salt, and pepper until smooth.
Place the pre cooked pulled pork in a large skillet over medium heat. Add a few tablespoons of water or broth if it looks dry. Cook, stirring occasionally, until heated through.
Pour the Carolina Gold sauce over the warm pork. Stir to coat evenly and let it simmer for 2 to 3 minutes so the flavors soak in.
Spoon the saucy pulled pork onto toasted sandwich buns. Top with coleslaw if using and drizzle with extra sauce if desired. Serve immediately.
