Preheat oven to 400�F. In medium nonstick skillet, over medium high heat, cook and stir turkey, garlic and ginger 4 to 5 minutes or until turkey is no longer pink. Drain thoroughly. In medium bowl, combine turkey mixture, bok choy, onions, soy sauce, sherry and oil. On clean, dry counter, layer phyllo sheets into a stack and cut into 2 (18 x 18 cm) rectangles. Work with one rectangle of phyllo at a time. (Keep remaining phyllo covered with a damp cloth following package directions.) Coat rectangle of phyllo with nonstick cooking spray. On counter arrange phyllo sheet to that 18 cm side is parallel to counter edge. Place quarter cup of turkey mixture in 13 cm strip, 3 cm away from bottom and side edges of phyllo. Fold 3 cm bottom edge of phyllo over filling and fold longer edges of phyllo toward center; roll up, jelly roll style. Phyllo may break during rolling, but will hold filling once the roll is completed. Repeat process with remaining rectangles of phyllo and filling to make remaining spring rolls. Place rolls, seam side down, on 2 cookie sheets coated with nonstick cooking spray. Coat tops of rolls with nonstick cooking spray. Bake 14 to 16 minutes or until all surfaces of rolls are golden brown.
