For an extra depth of flavor, consider adding a tablespoon of smoked paprika to the BBQ sauce during the simmering process. If you prefer a spicier kick, increase the amount of hot pepper sauce or cayenne pepper to your taste. To prevent the meatballs from sticking to the baking rack, ensure the rack is well-coated with cooking spray. For a richer flavor, use a combination of sweet and savory BBQ sauces. Coleslaw and cheese are great complements to these sliders.
