It is good to pack this in the corner of a bento because it's strongly flavored. It is good as a side dish served between the main dishes too.
I wanted to use bamboo shoots because they were in season and I wanted to make something easy for bento.
The bamboo shoots will be more delicious if you boil them in rice bran or to put some rice in the water, but you can also use pre-boiled bamboo shoots.
Enjoy Japanese food around the world.
