Instructions

  1. Step 1: In a bowl, mix 1/2 lb ground beef, 1/4 cup breadcrumbs, 1/4 cup grated Parmesan, and 1 egg until combined. Form into 16 small meatballs (about 1-inch diameter).
  2. Step 2: Place meatballs on a parchment-lined baking sheet and bake at 375°F (190°C) for 15-18 minutes until golden and cooked through.
  3. Step 3: Warm 1/2 cup marinara sauce in a saucepan over medium heat for 5 minutes. Split each mini bun and spoon 2 tablespoons of warm sauce onto the bottom half. Place 4 meatballs on top, drizzle with remaining sauce, and cover with the top half.
