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 ;-)
Quiche is that one recipe that I love coming back to — it's easy to make, looks delicious and tastes heavenly :-) Plus, it allows me to come up with new fillings, which makes it very versatile!
Sweet potatoes are very smooth and creamy when boiled, then baked, and shallots add a crunchy texture. The combination of them is very mild and aromatic, so make sure you spice it up to your liking!
