Turkey Meatballs

I'm not Italian so it is not a requirement that I make amazing meatballs, however, these were pretty good. The taste was great and I love having another use for turkey in my recipe box.  I did have some trouble getting them to stay together but I think that has more to do with my lack of meatball skills and not the recipe.  If you make this let me know how yours turned out, I need pointers.

Turkey Meatballs:
(Food Network- Giada de Laurentiis) 

Ingredients:
1 small onion, grated
3 garlic cloves, minced
1 large egg
1/4 cup dried bread crumbs
3 tablespoons ketchup
1/4 cup chopped fresh Italian parsley leaves
1/4 cup grated Parmesan
1/4 cup grated Pecorino Romano
1 teaspoon salt
1 teaspoon black pepper
1 teaspoon garlic powder
1/4 teaspoon ground black pepper
1 pound ground turkey meat
3 tablespoons olive oil
26 ounces marinara sauce

Directions:

Add the onion, garlic, egg, bread crumbs, ketchup, parsley, Parmesan, Pecorino, salt and pepper to a large bowl and blend. Mix in the turkey. Shape the turkey mixture into 1 1/4-inch-diameter meatballs. Place on a large plate or baking sheet.

Heat the oil in a heavy large frying pan over medium-high heat. Add the meatballs and saute until browned on all sides, about 5 minutes. Turn off heat. Transfer the meatballs to a plate. Pour off any excess oil. Add the marinara sauce, about 3 cups. Return all the meatballs to the pan. Turn the heat to medium-low and simmer until the sauce thickens slightly and the flavors blend, 15 to 20 minutes. Season the sauce, to taste, with salt and pepper.
