Bento Mushrooms

Japanese Bento meals began as a convenient way to serve meals eaten on the run in the field or elsewhere.  They were intended to be eaten any time between breakfast and dinner.  Later, they became popular as a snack or meal eaten during an intermission at the theater.

And in the modern day, Bento is a whole department of Japanese cooking and a vehicle for packing school lunches or meals for office workers. Bento Mushrooms are a classic in New Year’s cuisine or Osechi Ryoori.
