When you make your own pasta, you will always end up with some scraps, even more if you make ravioli. You can easily recycle this leftover pasta to make maltagliati, meaning "poorly cut" in Italian, which was traditionally meant as food for the poor. We are way past that, and today you can enjoy rich texture and amazing flavor of your pasta without the social stigma ;-)
I think life is too short to keep the frozen salmon in the fridge! :-) So I made a teriyaki salmon bento, which was so fast to cook, that I had too much idle time in the morning... Just be careful not to overcook the teriyaki sauce, because it may have a burnt taste. Also, optional lotus root slices will keep the fish tender and juicy for the time when you can finally devour every last bit of it ;-)
Tuna paste is ridiculously easy to prepare and makes a great no cooking bento, cutting the preparation time to less than 20 minutes, including rice cooking time! Now, that's what I would call cooking on the go! You can also use the tuna paste for a great tasting onigiri or sushi.
Bento is not only rice, but also other ingredients, like... pasta. This recipe came to life when I had some uncooked beef left-overs and just wondered what to do with them. Cooking them as a part of bento was a great idea!
