In a large bowl, add the beef, egg, oil, cheese, breadcrumbs, garlic, salt, pepper, basil and oregano. Mix to combine, gently tossing a few times with your hands. Don’t overmix – it will result in tough meatballs! Form the meat into teaspoon-sized balls, 1/2-inch in diamter, or about that size. It will make about 30 meatballs at that size.
