For the meatballs: In a mixing bowl, add the ground beef, ricotta cheese, egg, sun-dried tomatoes, Parmigiano cheese, salt and pepper. Mix well until the ingredients are evenly distributed. With your hands, shape the meatballs into the size of golf balls and pat them down so they can evenly cook. For the wine sauce: In a large frying pan, heat the extra-virgin olive oil and add the garlic. Lightly dredge the meatballs in flour and add to the meatballs to the pan. Add the sun-dried tomatoes. Fry the meatballs until golden on the outside. Add the wine to deglaze the pan and let the wine reduce by 1/2 and thicken up. Let cook for an additional 5 minutes.
