This was an impromptu attempt to use up some turnip greens. I guess it is a kind of ohitashi. 1 small bunch turnip or other greens Boil until done to your liking, drain and chop 2 tbsp white miso 1 tbsp mustard powder about 1 tbsp mirin or cooking water, to smooth the sauce mix this together until smooth and mix in with the chopped greens This much mustard powder makes it very hot. You could cut back.
