I used to work with a guy who did time in Japan (while there teaching English his sister, not asked to, mailed him weed for Christmas). He said despite his life imploding, prison was very nice and orderly and the food was simple and good. Now I want to know what he ate, too...I want to try everything you've described. I ate a lot of barley stew growing up (Scottish) and mixing barley with brown rice sounds delicious.
