Baked fish and chips

Set the oven to Gas Mark 7 or 220°C. Put a baking tray into heat up for 20 mins. Dry the raw potato chips with a clean tea towel, then toss them in 1 tbs of the oil. Put them on the baking sheet and cook for about 30 mins, turning them once. Meanwhile, dust the fish with the flour, dip it in the egg and then coat in the breadcrumbs. Put on the baking tray with the chips, drizzle with the rest of the oil and bake for 15 mins. Serve with lemon wedges, salt, pepper and vinegar.
