While I do try to keep a good stash of pre-made food to quickly assemble bentos in the morning, sometimes I've just run out, or am not in the mood to use whatever I have in the freezer, or leftovers in the fridge. That doesn't mean it's not possible to assemble a bento quickly using fresh ingredients and pantry items. Here are a couple that I made last week. The only premade 'stash' I used was frozen brown rice.
I've been working on a some recipes which work when I just throw them together, but aren't quite ready for prime time publishing here. So the meantime here are a couple of bentos that are too similar to other bentos already shown here, but may be of interest to look at anyway. Both feature chicken recipes from the recent chicken mini-marathon.
