To assemble the sushi burger, place the nori sheet on a cutting board with the shiny side down. Spray lightly or sprinkle with water. Place 1/4 cup of the rice in the middle of the nori. You may need to wet your fingers with water to help press down the rice onto the nori sheet. Top the rice with 1/4 cup spinach, a few slices of cucumber, half of the mint, and the Hilary’s burger. Next, add a few slices of avocado, the rest of the mint, a few slices of cucumber, the rest of the spinach and the last of the rice.
