To prepare bok choy, remove stems and center ribs from bok choy; cut large leaves in half lengthwise. Heat 1 can of broth in a large skillet over medium-high heat; bring to a boil. Reduce heat, and simmer. Place 3 bok choy leaves in broth; cook 15 seconds or until wilted. Remove leaves from pan; cool. Repeat procedure with remaining leaves. Reserve broth in pan.
To prepare stuffing, combine turkey and next 10 ingredients (turkey through black pepper) in a large bowl. Spoon 1 rounded tablespoon turkey mixture onto center of each leaf. Bring 2 opposite points of leaf to center; fold over filling. Beginning at 1 short side, roll up leaf tightly, jelly roll fashion.
Carefully arrange stuffed leaves, seam sides down, in a single layer in broth. Repeat procedure with remaining turkey mixture and leaves. Bring to a boil. Cover, reduce heat to medium-low, and cook 30 minutes.
To prepare dipping sauce, combine soy sauce and remaining ingredients. Serve with stuffed leaves.
