Brush a non-stick baking sheet with the remaining oil. Dip the fish strips into the egg, then coat them with the breadcrumbs. Transfer to the baking sheet. Bake for 25 mins until golden. The fish fingers are very delicate so lift them carefully off the tray with a spatula. Serve with their favourite vegetables and the chunky chips. You can open freeze the fish fingers on a baking tray, then once frozen transfer to a freezer bag. Cook from frozen at 200C/180C fan/gas 6 for 20 – 25 mins until crisp and cooked all the way through.
