Finely chop the garlic and sauté it in olive oil for 2 minutes until fragrant.

In a large bowl, combine ground beef, ground pork, ground veal, eggs, Parmesan cheese, bread crumbs, parsley, salt, and pepper.

Mix the ingredients thoroughly until well-combined.

Roll the mixture into golf ball-sized meatballs.

Heat olive oil in a large sauté pan over medium heat.

Add the meatballs to the pan.

Fry the meatballs, cooking on each side until lightly browned, approximately 10-15 minutes. Do not cook all the way through.

Transfer the browned meatballs to a pot of tomato sauce.

Simmer the meatballs in the tomato sauce on medium-low heat for about 45 minutes, or until cooked through.
