In a large mixing bowl combine first 6 ingredients. Check for seasoning. Using a sushi mat, place one sheet of nori, shiny side down. Lay down a thin layer of noodle mix on the bottom third of the nori. Arrange cucumber and peppers on the noodles and roll tightly. Moisten the top edge of the nori to "glue" the roll.
Plating: Slice sushi with straight cuts and some on the bias. Drizzle soy syrup and wasabi oil on a large, white plate. Garnish with gari, sliced scallions and sesame seeds.
Wasabi Oil: In a stainless steel bowl, whisk wasabi, mirin, and sugar. Add water until a loose puree is achieved. Whisk in oil. For extra spicy, use less oil.;
Soy Syrup: Combine all and reduce at a simmer until a syrup consistency is achieved, about a 70 percent reduction. Let cool.
