Place parsley, bell pepper, relish, herbs, salt, pepper and egg whites in food processor fitted with metal chopping blade. Cover and pulse until bell pepper is finely minced. Add turkey and plain oatmeal; pulse 2 or 3 times, until just mixed. Chill mixture 15 minutes. Preheat oven to 325 degrees. Use a spoon to form oval, egg-shaped meatballs (about 1.5 oz. per egg). Heat olive oil in nonstick skillet over medium heat. Brown meatballs on all sides, and place on nonstick baking sheet. Bake until juices run clear (about 10 to 15 minutes). Serve warm, sliced into quarters, with dipping sauce.
