# Directions:
01 - Preheat oven to 400°F. In a large bowl, combine ground beef, ground pork, egg, breadcrumbs, milk, Parmesan, garlic, parsley, oregano, salt, and black pepper. Mix gently until just combined.
02 - Shape the mixture into 16 meatballs, each about 1¼ inches in diameter. Arrange on a parchment-lined baking tray and bake for 15 to 18 minutes until browned and cooked through.
03 - While meatballs bake, heat olive oil in a saucepan over medium heat. Sauté onion until softened, about 3 minutes, then add garlic and cook another minute. Pour in marinara sauce and bring to a simmer.
04 - Transfer baked meatballs to the simmering sauce. Cook gently for 10 minutes, stirring occasionally to meld flavors.
05 - Optionally, slice rolls lengthwise and spread with butter. Toast under a broiler or in a pan until golden and crisp.
06 - Place four meatballs with sauce inside each roll. Top with two slices of provolone cheese per sandwich.
07 - Arrange assembled sandwiches on a baking tray and broil for 2 to 3 minutes until cheese is melted and bubbly. Garnish with fresh basil or parsley and serve hot.
