Preheat the oven to 375F.

In a large bowl, mix together the pork, beef, egg, Parmesan and seasonings.

Cut the cheese strings into small pieces.

Take a small handful of the meat mixture and place a piece of the cheese string inside. Form the meat around the cheese in a ball shape. This recipe makes approximately 24 meatballs.

Place the meatballs onto a baking sheet lined with foil and cook for 15-20 minutes until the meat is cooked and the cheese has melted.
