How to Make It
Combine first 5 ingredients in a small bowl, stirring with a whisk.
Coarsely chop bok choy leaves, and arrange on one end of a jelly-roll pan. Coarsely chop bok choy stems and arrange in a single layer on opposite end of jelly-roll pan. Place salmon, skin side down, in a single layer on top of leafy greens. Pour half of soy sauce mixture evenly over salmon; pour remaining half evenly over bok choy stems. Broil for 5 minutes; stir stems. Broil an additional 4 minutes or until desired degree of doneness. Arrange 1/3 cup bok choy on each of 4 plates. Top each serving with 1 fillet and 1 tablespoon green onions.
