1. In medium nonstick skillet, melt margarine. Add scallions; cook, stirring frequently, 2 minutes. Add mushrooms, pepper, savory and marjoram; stir-fry 4 minutes, until just tender, set aside. 2. Preheat oven to 400F. Cut each parchment square into a large heart shape and place on work surface. In medium bowl, combine snow peas, barley and rice. Divide barley mixture equally over one half of each heart; place bluefish on top of barley. Divide vegetables equally over bluefish; sprinkle with salt. 3. Fold parchment loosely to enclose filling. Starting at one end turn edges together in overlapping folds to make a tight seal. Place packets on baking sheet. Bake 12 minutes, until puffed. 4. To serve, place packets on dinner plates; slit open carefully and fold top parchment back.
