Combine ground beef, veal, and pork in a large bowl. Add eggs, cheese, parsley, minced garlic, and salt and pepper to taste. Using your hands, blend ingredients together.
Add the bread crumbs into meat mixture and combine. Slowly add water until the mixture is quite moist.
Shape the meat mixture into balls (2 1/2 to 3 inch balls).
Heat the oil in a large sauté pan and saute the smashed garlic clove until lightly brown to flavor the oil, and remove with a slotted spoon and discard.
Fry the meatballs in batches.
When the bottom half of the meatball is very brown and slightly crisp, turn and cook the other half.
Remove from heat and drain on paper towels.
Lower cooked meatballs into simmering marinara Sauce and cook for 15 minutes.
Serve over pasta, on a sandwich, or on their own.
