Cold Noodle Salad with Smoky Sesame-Citron Sauce

This is a popular snack in Japan in the summer and I think that you, too, will appreciate its refreshing qualities on a warm day. Make the sauce in the cool of the previous evening if you like; it will keep well in the refrigerator for at least a week. The noodles, may be cooked and refrigerated, and the vegetables prepared hours ahead of mealtime, too.
