Method

• Preheat the oven to 190C
• Take two pieces of strong kitchen foil, roughly 25cm square, and brush them with the oil
• Season the fish fillets generously and place them on the foil – either two small fillets or one large one per parcel
• Divide the garlic and chilli between the fish add a squeeze of lemon juice and a good grinding of black pepper over each pile, then bring up the sides of the foil and scrunch them together tightly to form well-sealed but baggy parcels
• Place the parcels on a baking tray, transfer to the oven and bake for 15 minutes
• Serve immediately
