I never went to Uni but reckon if I did, fish finger sarnies would have been a staple diet of mine..
Here's my slightly upmarket fish finger sandwhich... Thai prawn, chilli & lemongrass fish cakes, melted jalapeno & garlic cheese, dijonnaise mustard, toms and gem lettace in a toasted bap..
I like blind love! Lol. These look good - Ed's the same as you, said if he was ever stranded on a desert island and had one thing to take, it would be fish finger sarnies :-)
