Bento! #84 - Yuzukoshou Hanbaagu

Or "Yuzukoshou Burger." With "M" size rice, this is only 399 yen from the school cafeteria. According to Wikipedia,

Yuzukoshō (柚子胡椒?, also yuzugoshō) is a type of Japanese seasoning. It is a paste made from chili peppers, yuzu peel and salt, which is then allowed to ferment.[1] It is usually used as a condiment for nabemono dishes, miso soup, and sashimi. The most famous types of yuzukoshō come from Kyushu, where it is a local specialty.

Yuzu is by the way a kind of citrus fruit found in East Asia. According to me:

Yuzukoshō Burger is sweet, sour, and yummy.

Also, this one had a rather huge, larger-than-usual burger patty. It's not 100% beef though, of course. It came with some lettuce and a cherry tomato. I dressed the lettuce with some Italian Dressing which I think complemented the Yuzukoshou sauce quite well.

Speaking of beef, I think I might have said in previous posts that the Pawaa Don (Power Rice Bowl) is like gyuudon (beef rice bowl) with egg. It actually contains pork, not beef.
