torakris, thanks as always. Soba, you are of course correct. Certainly sauteed ingredients or "oily, fatty" foods might be cooked together with miso. But miso shiru at its best is at its simplest. Grilling is a much more palatable cooking method than sauteeing for Japanese cuisine which is essentially water-based, while Chinese is oil-based, French is butter-based, Italian is butter or EVOO depending upon region, and British food is, um, suety.
