Let the roast rest a few minutes before shredding to keep it juicy. Use sturdy hoagie or French rolls so they hold up to the dipping sauce. For extra flavor, add sliced onions or bell peppers to the slow cooker while cooking. You can also spread garlic butter on the rolls before broiling for extra richness.
