Usuyaki Tamago literally means "thin grilled egg," and as the name would suggest, it's a thin Japanese omelette prepared similarly to crepes. It's not a dish that's eaten on its own, but the thin golden sheets are used as a decorative wrapper for everything from onigiri to sushi to omurice. It can also be used like a tortilla, to make a colorful roll-up stuffed with meat, cheese, and vegetables.
