Chef's Tip: I make the meatballs ahead of time (about 100), and freeze them. That way I always have some on hand for unexpected parties.
Place a rack in the middle position, and preheat the oven to 375f (190c).
Add the sauce and the meatballs to a skillet (I use cast iron).
Chef’s Note: If this skillet looks familiar it’s the ones that they use at Holiday Inns to serve their skillet breakfasts. When one of the inns closed, I picked up about 15 of them. The diameter of the skillet is 6 inches (15cm).
Chef’s Tip: To make this a one-dish recipe, the skillet will be used for the serving/presentation.
Slowly bring up to a simmer, about 5 to 7 minutes.
Remove from heat, and top with the mozzarella.
Place in the oven and bake until the cheese begins to brown, about 8 to 10 minutes.
Place the skillet on a heatproof trivet, and serve with some nice crusty Italian bread. Enjoy
