Prepare a bamboo sushi mat* by wrapping in cling film to prevent rice sticking. Start by placing nori sheet shiny side down on mat. Using wet hands (to prevent sticking) place ¼-⅓ cup sushi rice on nori sheet. Spread evenly over nori sheet, wetting hands more if necessary, and adding more rice if needed.
Flip rice side over (if you want OR don’t to keep rice inside roll) add in filling starting with a few teaspoons spicy tuna near closest edge to you. Lay 3-4 slices avocados on top and then a few sticks carrots and cucumbers in front. Spread filling evenly, lengthwise on sheet.
Make sure fillings are close to each other. To start rolling bring nori sheet to the edge of sushi mat closest to you. Start with one roll to bring fillings tightly together, unwrap sushi mat, then continue rolling sushi with sushi mat until completely rolled. Press tightly and evenly to shape into even roll. Unwrap roll then wrap one more time to tightly bring roll together.
Assemble all the rolls then you can cut. To cut, run a sharp knife under water then wipe with damp paper towel to keep it wet (but not dripping).
On a plastic cutting board cut the sushi roll in half quickly, then cut each half into quarters to get a total of 8 pieces per roll.
Drizzle with unagi sauce and spicy Mayo (made with a 2:1 Mayo:sriracha ratio) and garnish with sesame seeds (optional). Serve immediately.
Enjoy!
