Wasabi gives a lively bite to this colorful salad. Either snow pea or sunflower sprouts (both available at well-stocked supermarkets) are equally good in this.
Combine cabbage, sprouts and radishes in large bowl. Remove peel and all white pith from oranges with sharp paring knife. Cut segments free from membranes, then cut segments crosswise into 1/2-inch pieces, and add to bowl.
To make Sesame-Wasabi Dressing: Whisk all ingredients in bowl; pour over salad, and mix to wilt sprouts. Let stand 10 minutes, tossing occasionally.
Meanwhile, toast sesame seeds in dry skillet over medium heat about 3 minutes, or until golden and fragrant. Sprinkle sesame seeds over salad; serve.
