This reminds me of the dressing on the salad in the bento boxes at the Japanese chain Asakaze here in Sydney. It's light and refreshing. Please note Australian recipe 1Tbs=20mls. If your miso is very thick, it can be easier to put it in a small bowl and gradually stir in the other ingredients a little at a time so that it doesn't get lumpy. Really needs the sesame seeds at the end and a little goes a long way.
