Sauce:

1. Using an 8-quart stockpot (or similar) add 2 cans of tomato sauce and one can of tomato paste, stir to combine.  Add 24 ounces of water, stir to fully combine with the tomato sauce.
2. Turn the stove burner to medium.
3. Add the garlic, oregano, thyme, basil, and red pepper flake to the stockpot.  Stir to combine all ingredients.
4. Once the sauce heats to a low simmer, turn the heat down to medium-low and maintain a simmer.

Meatballs:

1. In a large mixing bowl, add the Italian sausage, ground beef, parmesan cheese, crushed crackers, garlic, eggs, milk, kosher salt, and fresh ground pepper.  Mix to combine, using caution not to overwork the meat mixture.
2. Measure the meat mixture into 3 ounce portions and form into 2 inch meatballs.  Add the formed meatballs into simmering sauce by simply dropping them into the sauce.  Don’t stir the meatballs into the sauce as you make them.
3. After all the meatballs are formed and added to the sauce, GENTLY stir the meatballs to cover them all with sauce.
4. Allow the meatballs to simmer in the sauce, covered, for 2 hours, stirring once after about an hour.
5. Skim the rendered fat from the surface of the sauce.
6. Stir the meatballs and lower the heat to low.

Preparing the Rolls:

1. In a small frying pan (or sauté pan), melt the butter.  Add the crushed garlic, oregano and basil.  Lower the heat to maintain a low simmer using caution not to burn the butter.
2. Using a very sharp knife, make a ‘V’ cut around the top of the roll. Remove the section inside the cut area.
3. Turn on the broiler in your oven.  Using a basting or pastry brush, apply the garlic butter mixture to the inside of the cut rolls.
4. Place the rolls under a broiler.  Cook until just beginning to brown.  Remove the toasted rolls from oven, turn the oven to 400° F, then place two slices of provolone cheese onto the roll to cover the removed area.  Return to oven for 2 minutes to begin melting the cheese.

Assembling the Sandwiches:

1. Drizzle a tablespoon of sauce over the cheese.  Then arrange 3 meatballs evenly onto each of the rolls.  Sprinkle shredded mozzarella cheese over each sandwich.
2. Place in oven until the cheese is melted.
3. Serve immediately.
