buying lunch at school is way too expensive so I have started making onigiri for lunch. Its cheap easy and extremely filling (2 for lunch). Seeing as how I don't like to put my rice in the fridge overnight, I leave my onigiri out all night in its mold so it doesn't dry out as much.
do you have any good filling ideas that don't need constant refridgeration? I'm not that concerned with food safety - for example I'll leave out pizza at room temp over night, but I will not do this with raw meat.
so far I have made miso stuffed and bonito soaked in shoyu. does anyone have a good recipe for spicy tuna?
