I first ate this simple salad in an Osaka 7-11 store and I fell in love. I hope you and your family will find this recipe as delightful and satisfying as I do. The bonito flakes add a smokey flavor and look lovely dancing as the salad is presented. Silken tofu and toasted sesame oil can be added to turn this side dish into a dinner salad. Hijiki could be a delicious substitution for wakame, and shredded nori could be used in a pinch.
