This casserole is simple and delicious, and makes a perfect snack during a picnic (bento anyone?)—you should use it as a basic idea for a casserole, since the pasta sauce is the stable and the most important piece of the meal. It's also a very tweak-able recipe! :-)
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 didn't plan to make this cake at all, what I did plan was apple tart with apricot jelly... Well, sometimes I just change my mind, especially while experimenting in the kitchen :-) The result is interesting, refreshing and citrusy! :-) If you don't like the strong orange aroma, you can replace them with any soft and sweet fruit: peaches, pears, and apricots should do fine!
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!
