Very simple side dish. Just stir-fry some sliced onions in a little sesame oil, 
throw in about a tablespoonful of roasted sesame seeds, 
add the cleaned-up bean sprouts (oops, I missed some root tips there), 
sprinkle a little bit of mirin and a pinch of sugar and salt. Keep stirring, letting the sprouts wilt just a little bit and the mirin's alcohol to evaporate. And it's done!
