Rinse 2 cups of sushi rice under cold running water until it runs clear. Cook according to package instructions or in a rice cooker. Once cooked, combine with ¼ cup of rice vinegar and a pinch of salt. Stir gently and let it cool.

While the rice cools, take the sliced tofu and marinate it in the teriyaki sauce for at least 15 minutes.

In a non-stick skillet over medium heat, fry the marinated tofu slices for about 4-5 minutes on each side until golden and slightly crispy. Remove from the heat and set aside.

Wet your hands to prevent the rice from sticking. Take a small handful of sushi rice and mold it into an oval shape. Place a slice of cooked tofu on top, pressing gently to ensure it holds together.

Sprinkle sesame seeds and crispy shallots over the tofu. For an added touch, place a small strip of nori on the side or wrap it around the nugget.

Arrange your beautifully crafted nigiri on a plate, and serve with extra teriyaki sauce if desired.
