Prepare all vegetables by cutting into very fine and even strips to fit the length of the nori and cucumber.
Cut the cucumber so it's flat on both ends and about 4" long. Use an apple corer to bore down the center, making a cucumber tube, set aside.
Take a single half-sheet of nori, adding ingredients of your choice -- do not overstuff! Roll up and insert into the hole in the center of the cucumber.
Take a sharp knife and slice the cucumber into bite-sized rounds. Serve immediately with sesame miso ginger sauce, store any leftovers in the fridge.
