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! :-)
I think life is too short to keep the frozen salmon in the fridge! :-) So I made a teriyaki salmon bento, which was so fast to cook, that I had too much idle time in the morning... Just be careful not to overcook the teriyaki sauce, because it may have a burnt taste. Also, optional lotus root slices will keep the fish tender and juicy for the time when you can finally devour every last bit of it ;-)
This simple recipe requires only 3 ingredients: sliced pork loin (already mentioned minute steaks or easy steaks), shallots and teriyaki sauce. It's also one of the lazy recipes — part of it you can prepare evening before, and finish it quickly before serving or packing your bento box. Plus, marinating for a long time allows increased flavors to transfer easily across the meat!
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!
