This Tuesday was the first day of work (aka hatsus-shigoto 初仕事), furthermore after new year there are always left over ingredients. This is a good time to make bento to bring to work.
This bento is not difficult to make, it was just some egg with Pork and Vegetable. Maybe next time we will have the recipe for each of the items in the bento.
A bento is easy to bring to work or school, it don't need a lot of them to make also. Making a good bento will ensure a balance diet and hopefully the person who you made the bento for will appreciate your effort.
I know overseas where I used to base don't have the habit. There are just simply too many food centre and food courts where large variety of food will be served. Even in school, every school has a school canteen.
