Heat a nonstick skillet over high heat; add enough olive oil to coat skillet Using a medium/large ice cream/cookie scoop, shape the meatballs and then drop them directly into the pan. Cook for 30 seconds or until browned, then flip over. Cook them on the other side for 30 seconds or until browned, then transfer to a baking sheet lined with parchment or foil. Repeat with remaining meat. With a medium-sized scoop you should end up with 24 meatballs; a large scoop will yield about 15.
