Crispy Rice Sushi Donut

Preheat oven to 400 Fahrenheit. In a large bowl, combine cooked sushi rice with 1 tablespoon rice wine vinegar, sesame oil, mirin, and salt. Mix to evenly coat rice. Spray cooking spray in a donut mold. Spread the rice mixture in the donut molds and press down so the donuts are tightly packed. Bake for about 15 minutes, until the rice is lightly golden - this helps the donut shape hold together better! Top the donuts with strips of tuna, salmon, cucumber, and avocado. Garnish with sesame seeds and scallions. Serve with soy sauce and enjoy!
