Preparation
Step 1
For Peperonata:
Warm oil and butter in a large skillet over medium-high heat. Add onions and peppers and cook over high heat 4 minutes. Stir in minced garlic, cook 30 seconds. Simmer 5 minutes until cooked through. Remove from heat and season to taste.
For Meatballs:
Soak bread in water to cover, 5 minutes. Squeeze out excess water.
Combine soaked bread, beef, prosciutto, sausage, eggs, Parmigiano-Reggiano, nutmeg, ¼ cup of the Pecorino, ¼ cup of the parsley, and ¼ cup of the olive oil in a large bowl and mix very gently with your hands. Season with salt and pepper. Form mixture into 2-inch balls. Place balls on a baking sheet, cover, and refrigerate 1 hour to allow flavors to blend.
Warm remaining ¼ cup olive oil in a 10- to 12-inch heavy-bottomed skillet over high heat until almost smoking. Brown meatballs on all sides. Transfer to a plate and drain oil from pan.
Add tomato sauce and wine to the pan and bring to a boil. Place meatballs in sauce and return to a boil, then reduce heat and simmer 30 minutes.
Slice open hero rolls and fill each with 3 meatballs and sauce. Top with each with provolone cheese and some peperonata. Transfer sandwiches to a platter and serve with remaining ¼ cup Pecorino and ½ cup parsley sprinkled over the top.
