Step 1Heat the oven to 400 degrees.
Step 2Place each fish filet on a large sheet of parchment paper or foil that has been placed on a baking sheet. Evenly distribute the ginger, green onions, bok choy, cilantro, straw mushrooms and garlic over the fish.
Step 3Combine the soy sauce, sugar and lime juice in a small bowl and stir until the sugar dissolves, about 1 minute. Pour the sauce over the fish and vegetables then fold up the paper or foil securely to seal. Bake until the fish flakes, about 15 minutes.
