To prepare the sauce, combine first 7 ingredients in a small bowl. Chill.
To prepare the cakes, place bread in a food processor, and pulse 10 times or until coarse crumbs form to measure 1 1/4 cups. Set aside. Combine the turkey and next 5 ingredients (turkey through egg whites). Stir in the breadcrumbs. Divide turkey mixture into 8 equal portions, shaping each into a 1/2-inch-thick patty. Heat oil in a large nonstick skillet coated with cooking spray over medium heat. Add patties; cook 5 minutes. Turn patties over; cook 5 minutes or until golden brown. Serve with sauce.
