Mix all ingredients in a large bowl. User your hands and pretend you're back in grade school.
Form into balls. An ice-cream scooper helps with consistent portioning. l like golf-ball sized ones - but your balls, your call!
Heat up some oil in a pan and brown the balls on all sides (Ok, most sides; kind of hard to brown every side of a circle). Whether they need to be cooked through at this stage depends on if you plan to incorporate them into a sauce or something else. I usually make these and throw them into the last 20-30 minutes of the Basic Red Sauce for a classic spaghetti and meatballs.
