1 teaspoon Nama Shoyu or Braggs
1 teaspoon wasabi paste
3 tablespoon apple cider vinegar
1 tablespoon raw clover honey (save the bees!)
Blend everything well and pour on salad :)
Make sure that you use wasabi powder with no salt, preservatives, etc. I use Sushi Sonic brand which contains 45% genuine wasabi and also includes horseradish and mustard powder. Its not cheap, but it is well worth it.
