it sounds awesome, but also sounds like it could get expensive. I would love to do this, but I don't think I have that kinda of time. How long does it take to assemble a bento lunch?
It actually not that expensive. bento boxes can be very inexpensive, usually less than $20. bento accessories usually run aroun $1-$5 each. If ypu collect them slowly then its really not that bad.
bento assembling time really depends. Some elements can be prepared ahead of time like cutting the veggies, cooking the main dish, etc. other things like the rice should be prepared the morning of. (I have an awesome rice cooker that I can program so that my rice finishes cooking at a certain time. So I can prepare it the night before and it will finish cooking just as I am starting to put together the lunches) Probably at the beginning it takes a lot of time. I usually do bentos on the weekends, because I can be a bit lazier....
really if you have the leftovers it takes no time at all. I made a lunch for my mom in just about half an hour. I made fried rice, put in in the bento box, sliced some chicken from the night before and arranged it over the rice, sliced a kiwi and put it in a small side dish cup I had already fitted into the bento box. simple and fast!
