If you have as many meatballs coming out of your ears as I did from the Rigatoni these sandwiches are the perfect solution.  If you decide just to make them from no leftovers I have a little easier recipe.  Instead of making your own sauce just use a jar of the store bought.  It is simple but delicious!

Ingredients:

• 1 pound Ground Chuck Or Ground Beef
• 1/2 cup Panko Or Other Bread Crumbs
• 1 clove Garlic, Minced
• 1/2 teaspoon Salt
• Freshly Ground Black Pepper
• 1/2 cup Milk
• 2 Tablespoons Olive Oil
• 1/2 whole Medium Onion, Diced
• 1 jar (large) Marinara Sauce
• 12 whole Dinner Rolls (or Slider Rolls)
• 4 slices Provolone Cheese or Mozzarella, Cut Into Four Wedges Each

Directions:

Mix meat with bread crumbs, garlic, salt, pepper, and milk. Knead together with hands. Roll into heaping tablespoon-sized rolls. Heat olive oil in a large skillet over medium heat. Add onions and cook for one minute. Add meatballs between the onions and brown for one minute. (You might have to do this in two batches, depending on the size of your skillet.) Pour in jar of marinara; shake pan gently to mix. Put on lid and allow to simmer for 20 minutes. When ready to serve, cut each dinner roll in half. Place a wedge of Provolone on the top and bottom of each roll. Spoon a meatball with the sauce onto the bottom bun; top with the top bun. Serve immediately!
