In a large bowl, add ground beef, egg, oil, cheese, breadcrumbs, garlic, salt, pepper, basil and parsley. Mix to combine, gently tossing a few times with your hands. Don’t overmix – it will result in tough meatballs! Using a teaspoon measuring spoon, roll mixture into small meatballs, about the diameter of a nickel or so. Place in the baking dish and bake for 20 minutes.
