These King's Hawaiian Roll Meatball Sliders feature savory meatballs topped with a rich marinara sauce and gooey mozzarella cheese and then finished with zesty garlic butter.
Step 1: Preheat oven to 350 degrees.
Step 2: Add cooked meatballs to a saucepan with marinara sauce. Heat over low heat until the meatballs are warmed through.
Step 6: Mix melted butter, garlic powder, and oregano in a small bowl.
Step 7: Spread the butter mixture over the tops of the rolls. Bake covered for 10 minutes. Remove the cover and bake for an additional 5-10 minutes or until the cheese is melted and the top of the bun is golden brown.
