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! :-)
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! ;-)
There is literally no easier recipe in the world, that tastes so good and takes only few minutes to cook, including rice cooking time! I always do it during hot summer days, because it's a no-brainer.
You can serve it as a main dish with more fancy toppings, or as a side dish, but also it's a great addition to bento or a small snack!
