I came across this amazing fishcake recipe by BBC GoodFood that uses things you'll most likely have in your storecupboard/pantry. No bread crumbs needed!
The website it came from said it would take under 30 minutes but I would give it 45/50 minutes to prep and cook. I also did not have any fresh lemons or chives so I substituted them for pre-squeezed lemon juice and dried tarragon instead.
I'm very happy with the out come and would definitely make these again, I have attached pictures to show you the process. Please post pictures if you try this out, hopefully they will look prettier than mine.
Put the potatoes in a saucepan, cover in cold, salted water and bring to the boil. Once boiling reduce to a simmer and cook for about 8 mins until tender. Drain and leave to steam-dry for 2 mins.
Mash the potatoes in a large bowl. Add the tuna and combine, breaking it up with a fork, then add the lemon juice and chives. Season well, add the egg and use your hands to bring everything together. Divide the mixture into 6 and shape into fishcakes. Chill for 10 mins to firm up.
