In a small bowl, combine the ginger, garlic, scallions, sesame oil, and orange zest. Divide the mixture and pat evenly on the fish fillets. Sprinkle with salt and pepper.
Lay a fillet in the center of an 8-inch sheet of plastic. Fold the plastic to create a tight package. Repeat with the other fillets.
Steam the fillets over simmering water for about 12 to 14 minutes, depending on the thickness of the fillets. Unwrap the fillets and transfer to a serving plate, pouring any steaming juices from the plastic over the fish.
