We had a leisurely morning one day and decided to stay home for lunch. We took advantage of some food Hiromi's parents had sent us away with, all acquired at a supermarket.
The souzai (side dish) set, ready to eat, included several small portions of simple dishes that are easily prepared in bulk, but rather time consuming to do in small quantities. At home I've made some variation of almost all of these dishes, but rarely all for the same meal.
I don't usually buy a lot of convenience foods in the U.S.
Some sweet-savory beans, tamagoyaki, kabocha no nimono (simmered squash), one aemono, a little hijiki with moyashi, and two other simple nimono. One contained gobo (burdock root), daikon, carrot and ganmodoki. The other is a mildly seasoned satoimo (small taro potato) dish with scallions and a little bit of yuzu peel.
We also had some black sesame, starch-thickened, gomadoufu, which came with a little sauce packet.
We only needed to prepare a little rice to accompany this to have a fairly decent everyday meal.
