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 is one of my signature dishes—it's delicious, rich and hearty, and goes well with any kind of base: pasta, potatoes, and rice just taste superb together. My secret to the intensive, flavorful sauce is the triple reduction of the ingredients' fluids, due to cooking in batches and mixing in specific order. It takes some time, but the result is so much worth it! :-)
Can you imagine, there was the time I didn't want to eat sushi, because of the raw fish?! Well, that's true, shame on me. Lots of shame. On me. Agreed...
Knowing that, I decided to make a recipe for sushi-like rolls, that look and taste close to sushi, but... are not raw! Nothing in this recipe is raw, and that also means that you can keep them safe longer at the room temperature, place in your bento, take for a picnic or just offer them as a healthy snack for people didn't discover yet the ingenuity of Japanese cuisine! ;-)
The bare tuna-paste bento was a great success, but with the arrival of my new bento container, I was left with some extra unused space. I decided to fill the space with easy to make and very tasty iri tamago, which is basically a Japanese kind of scrambled eggs! You can definitely use iri tamago in onigiri, or as a small side dish.
