This is a version of sushi that I have only seen in Hawaii - hotdog sushi. This recipe is a tribute to Eileen Chow who we fondly referred to as "Glen's Grandma". She was making hotdog sushi when nobody else was doing it and in her version, she would cut the hotdog in half and fill it with spicy Chinese hot mustard. This is an easier version as everything she made was from scratch.
Cook rice, once rice is finished cooking and has rested for 20 minutes, season rice with sushi seasoning packet in a bowl. Par steam hotdogs for a couple of minutes. Allow to cool. Prepare hot mustard if necessary. Cut hot dogs in half but not all the way through. Press rice on to nori, place a hot dog at top, fill with spicy mustard, and roll into sushi roll. Allow to sit for 15-20 minutes before cutting with a wet knife. Serve with Chinese hot mustard and shoyu on the side.
