Place 2 cups hot water in a steamer. Place the fish in the steamer and top with the ginger and green onions. Steam, covered, for 8 to 9 minutes.
In a small saucepan, bring the oil to a gentle boil. Remove the fish from the steamer with a flexible nonstick spatula. Place fish on a deep platter or one with an edge. Pour hot oil over fish for a sizzling presentation. Garnish with fresh lemon or lime wedges. Serve immediately.
