Make your own Ahi Tuna Hand Roll !!

The host, Singhi, was showing us (well, primarily me...the new gal!) how to make the Ahi Tuna handroll ! Singhi also shared with me, that there are different types of Ahi Tuna grade and that there is a type of tuna, that is caught in Japan where they sell the sushi for about $ 30-40 per sushi !! (per sushi = 2 pieces of tuna pieces over rice !! crazy!!) There is a japanese term for this "upscale japan tuna" but don't remember...maybe I had too many wine glasses already!
