In a small bowl, whisk the wasabi sauce, soy sauce, rice vinegar, sesame oil, garlic and ginger.

In a large bowl or deep platter, layer the lettuce, cabbage, scallions, cilantro, straw mushrooms and bean sprouts.  Drizzle on dressing, use as much as desired.

Nutrition note: I try and keep my dressings light, so I actually only used half the amount listed, but I know it wouldn't be enough for many people and it is still just a little over 100 calories for the salad.
