Preheat a medium skillet over medium high heat. Combine meats, onion, parsley, salt, and pepper. Add butter and oil to pan. Roll small, bite-size balls, adding meatballs to pan as you roll them. Cook balls 10 to 12 minutes, shaking pan occasionally to brown equally on all sides. Deglaze pan with Vineyard Creek Sauvignon Blanc and allow wine to reduce by half, 1 or 2 minutes. Remove pan from heat and squeeze the juice of 1/2 lemon over the meatballs.
