Fry the fish fingers according to the instructions. Cut the rolls open and brush with the tartar sauce and ketchup.
Cut the onions into slices and spread them on the lower side of the roll. Cover each with a lettuce leaf, 3 fish fingers and a few slices of the pickled cucumbers. Place the top half of the bun on top.
Super delicious, my kids love it, and if you have to go fast this is a good alternative and most importantly, it`s not always the same way of serving fish fingers!
