Sushi Bread

I think you may be referring to a popular dish commonly found in Japanese-American restaurants in the USA, not actually called "sushi bread." After some research, I'm going to take a educated guess:

Are you perhaps thinking of "Teriyaki Chicken Sandwich" or "Sushi Burger" (also known as "Sushi Bun" or "Rice Burger")?

Here's what I think you might be looking for:

Sushi Burger (or Sushi Bun):

In some Japanese-American restaurants, you can find a unique fusion dish called Sushi Burger or Sushi Bun. It's a sandwich that replaces the traditional burger buns with a "bun" made of sushi rice, often filled with teriyaki chicken, beef, or other proteins. The sushi rice bun is typically toasted or grilled to give it a crispy texture.

Teriyaki Chicken Sandwich:

Another possibility is a Teriyaki Chicken Sandwich, which is a popular menu item in many Japanese-American restaurants. This dish typically consists of grilled or pan-seared chicken breast glazed with a sweet teriyaki sauce, served on a toasted bun (not made of sushi rice). The sandwich may be accompanied by lettuce, tomato, and other toppings.

If I'm correct, I'd be happy to provide more information or recipes for these dishes. If not, please give me more details or characteristics about the "sushi bread" you're thinking of, and I'll do my best to help you out!
