How to make it
Heat the oven to 200C/180C fan/gas 6.
Mix the marinade. Coat fish in the mixture.
Cut out 4 pieces of baking paper each about 30x50cm.
Mix the melted butter with 1 tsp Lee Kum Kee Premium Oyster Sauce, then add to the vegetables and toss together. Divide between the pieces of paper, then top with the fish and spoon over any remaining marinade.
Bring the long sides of the paper together at the top, fold over once then twist the sides to form parcels tucking the ends under the package.
Transfer to a baking tray and bake for 20 minutes until the fish is cooked. Timing will depend on the thickness of the fish. Serve.
