DEEP FRYING: Heat a pot/wok of oil (anywhere between 1-3 cups). Fry the meatballs until they are brown all over. If you put too much cheese, or if the cheese aren't finely chopped, the meatballs will stick to the wok and the spatula. Alternatively, during the marination, you could hold the cheese, and then add the cheese during shaping by stuffing them in the middle of the meatball.
