This is a wonderful side dish, and a rice cooker is used so you can concentrate on preparing the main dish, even better. I made this on 20 June 2018, perfect.
Place the first 5 ingredients in your rice cooker and mix evenly. Add the water. Set the cooker to the Cook setting. (After this photo, then the rice was added and mix together.)
When the cooker switches to Warm setting, fluff the rice with a spoon and taste, season with a pinch of salt if needed. Serve as a side with any main dish.
