Place the sheet of nori on a bamboo rolling mat. (if you do not have one you can use clingflim)
Spread the cooled sushi rice over the nori in a thin layer.
Cut very thin slices of fish. I used salmon and you can put in vegetables such as pepper and cucumber.
Place the fish and vegetables in the middle af the rice and nori
Starting with the edge nearest to you roll it very gently but tightly into a tight cylinder.
Pull the rolling mat away and you will find there will be a bit of the nori left. Get some wasbi and spread a very thin layer on it to seal the sushi together.
Get a very sharp knife and cut the sushi into small pieces.
Serve with soy sauce, oyster sause, wasabi etc :)
