Gluten-Free Pull-Apart Meatball Sliders

**1. Prepare the Meatballs:** In a large mixing bowl, combine the ground beef, sweet Italian sausage, gluten-free breadcrumbs, grated Parmesan cheese, eggs, whole milk, garlic powder, dried oregano, crushed red pepper flakes, salt, and freshly ground black pepper. Mix gently with your hands until well combined.

**2. Form the Meatballs:** Roll the meat mixture into 12 equal-sized meatballs, approximately 1.5 inches in diameter.

**3. Cook the Meatballs:** In a large skillet over medium heat, cook the meatballs in batches, turning occasionally, until they are browned on all sides and cooked through, about 8-10 minutes. Remove from heat and set aside.

**4. Prepare the Rolls:** Preheat your oven to 350°F (175°C). Place the gluten-free slider rolls on a baking sheet, keeping them connected. Using a serrated knife, carefully slice the entire batch of rolls horizontally, ensuring they remain attached at the sides.

**5. Assemble the Sliders:** Spread 1 cup of marinara sauce evenly over the bottom half of the rolls. Place one meatball on each roll, then spoon additional marinara sauce over the meatballs. Sprinkle the shredded mozzarella cheese evenly over the meatballs and sauce.

**6. Add the Top Half of Rolls:** Place the top half of the rolls over the assembled meatballs and cheese, pressing down gently to compact the sliders slightly.

**7. Prepare the Butter Mixture:** In a small bowl, melt the unsalted butter. Stir in 1 teaspoon of dried oregano and 0.5 teaspoon of crushed red pepper flakes.

**8. Brush with Butter:** Brush the melted butter mixture evenly over the top of the rolls.

**9. Bake:** Cover the baking sheet with aluminum foil and bake in the preheated oven for 15 minutes. Remove the foil and continue baking for an additional 10-15 minutes, or until the top is golden brown and the cheese is melted and bubbly.

**10. Serve:** Remove from the oven and let the sliders cool for a few minutes. Slice along the pre-made lines to separate the individual sliders. Serve warm and enjoy!
