I made omrice bentos the other day. Omrice -- omelet & rice -- is one of Japanese comfort foods. I always used to order it at a restaurant as a child. It was originally ketchup-flavored, fried chicken rice wrapped in a thin omelet with plenty of ketchup on it, but there are some styles of them nowadays. Mine is really simple (as always). I stir-fried cut chicken thigh and onion, then seasoned it with ketchup, salt, black pepper and butter. And then mixed it into fresh-cooked brown rice, then put scrambled egg (or an omelet) on it. I sometimes do a wrap version. I actually like it better.
