Mind you fish finger sales are huge in PL and have been for years.
Same in the U.S. where we call them "fish sticks".
Poor people's food that you put tarter sauce, onion or ketchup on to flavor them.
All they are is cheap minced fish of God only knows what kind pressed and shaped into fingers covered with bread crumbs,
They come frozen in a bag or box here. ($5 a kilo)
Pop them in the oven for 20 minutes on a cookie sheet and Walla, a child's delight.
Very easy meal to make by a worn-out father who has worked all day at his day job.
