Believe it or not as much as I love bento I've never given my kids octo-dogs. So I bought some nitrate free hot dogs from Trader Joe's and thought I would try it. Also at Trader Joe's was frozen yaki-onigiri. Now I've always just made regular onigiri or rice balls, so being as these were different and already made well I figured why not? Turns out my kids loved them! Also they even ate the cold octo- dogs. This was a pretty successful lunch overall but definitely an occasional one. A great recipe for yaki onigiri is found atlunch in a box. I think I will try making and freezing some myself.
