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! :-)
This recipe is very easy and fast to cook, because it requires ready-made teriyaki sauce. Still, it's a really tasty alternative to sausages and pork, and chicken made in teriyaki style is juicy, tender and full of aroma! It also takes just few minutes, because the meat is first fried quickly, and then glazed with sauce. Fast food like a boss ;-)
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!
