Take nori seaweed - and cut (with a knife or scissors) into strips one centimeter thick.
Cut or slice the extra toppings into thick and flat slices
With wet hands take a handful of rice and roll out a long "meatball" type line of rice.
Place the patty on a strip of seaweed (the rough side of seaweed on top).
Place the topping on the back of the rice (for those who would like - you can put some spicy mayonnaise and wasabi (prior) to help with gluing it all together - I love without)
Wet the seaweed with a little water (dip a finger into a bowl and spread on seaweed) - Close the seaweed on the rice and the chosen extra.
Simple as that!
Serve with spicy mayonnaise, sweet chili, soya sauce and enjoy!
