In a large bowl, thoroughly combine all the ingredients above except for the olive oil and mozzarella.
Using your hands, roll the meat into golf ball sized meatballs. With your finger make a hole in the center and place a cube of mozzarella.
Cover the cheese with the remaining meat, and shape into an oval.
Heat the olive oil in a large frying pan.
Fry the meatball for about 3 minutes on each side. Until meatballs are golden brown.
Drain on a paper towel and serve warm.
