In a large bowl, stir together the beef, onion, ½ cup of parsley, garlic, egg, basil, oregano, salt, and pepper until thoroughly combined.

Using your hands, pinch off palm-size pieces of the mixture and roll into meatballs. You’ll end up with 8 to 10 meatballs.

In a large frying pan over medium heat, heat the olive oil. Carefully add the meatballs to the pan, and brown on all surfaces, about 5 minutes per side.

Remove from the heat, garnish with the remaining 1 tablespoon of parsley, and serve.
