Add ground beef, ground pork, ground veal, eggs, chopped garlic cloves, parmesan cheese, oil, breadcrumbs, salt, parsley, and black pepper in a large bowl. Mix well. Roll into half-inch balls.

Saute meatballs in the oil.

In the same pan, make the sauce now. Heat oil, cook onions, tomatoes, and garlic, and season with bay leaves, red paprika, parsley, salt, and pepper.

Add meatballs to the sauce and cook for fifteen minutes. Discard bay leaves and parsley at last.

Meatballs are ready.
