TOMATO, TŌFU, OKRA, BONITO FLAKES and NORI
In Japan, tomatoes are often paired with tōfu in a dish known as hiya yakko.
Bonito flakes (katsuo-bushi also known as okaka) are often used to garnish fresh or briefly blanched vegetables. The fish flakes will be more smoky-aromatic if roasted in a dry skillet before crushing them.
Use this post devoted to okra to help you prepare it well.
Plain, or flavored (aji-tsuke) nori can be crumpled and sprinkled on top of tomatoes — a tart sesame-soy dressing goes well with this. Or, make nori tsukudani and use it as a sauce or dressing.
