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! :-)
Hot, savory and full or aroma, that's literally an omelette on steroids that smashes my hunger during dark, cold autumn days :-) It's also extremely easy and pretty fast to cook!
