When I brought this plate to the table everybody laughed, and it is a fun recipe! Finto pesce means fake fish, the original recipe is a kind of pate made with potatoes, mayonnaise, capers and canned tuna (I think very 1960s!). My Mother made it, we lived in the mountains far from the sea, so fish was rare (and frozen or canned). Of course being a vegetarian I don't use tuna for this recipe, but seaweed.

Brush and wash (but don't peel) 1 kg of mashing potatoes, then peel them and pass them through a potato ricer. Add a tbsp of capers, some nori seaweed, shredded, and a few tbsp of mayonnaise (to taste). Mix well. Shape into a fish and decorate with veggies and more nori ( I cut my nori with a flower cutter). Perfect for summer, and for kids!
