Sweet & mild shio-koji miso soup with sweet potatoes.It becomes a sort of easy pork soup if you add sliced and chopped pork.
I added pork to the miso soup with sweet potatoes. An easy pork soup.
You could add other vegetables to make it filling. Adjust the amount of miso to taste. It seems like the sweet potatoes become sweeter because of shio-koji and miso.
Enjoy Japanese food around the world.
