Heat a large frying pan with a little oil and gently, one by one, add in the meatballs. After they cook for about 4 minutes, flip the meatballs and cook an additional 4 minutes. Once they're cooked on the outside, they should be a little less delicate. Making sure none are stuck to the bottom, start tossing them in the pan a little more to cook them evenly. Drain most of the fat, leaving a few tablespoons worth in the pan.
