Tomato Katsuo Nigiri Sushi is a unique twist on traditional sushi, where fresh tomato slices are used instead of fish. The tomatoes are marinated in a flavorful mixture of soy sauce, mirin, and bonito flakes, giving them a savory and umami-rich taste. The tomato slices are then placed on top of seasoned sushi rice and garnished with a sprinkle of sesame seeds and green onions. This vegetarian sushi option is refreshing, light, and bursting with flavors.
