The magic of this recipe is that the mushrooms rehydrate with the marvelous taste of the marinade. If you do not have time to prepare the dehydrated mushrooms and nuts, plain mushrooms and nuts will work too.
In a large salad serving bowl, combine kale, onions, red pepper, sweet potato, garlic, ginger, lemon juice, oil, Namu Shoyu, and dehydrated mushrooms. Toss. Let the salad sit at room temperature for 1-2 hours. Toss again just before serving and top with nuts or seeds.
Note: To blanch kale, tear into bite size pieces, removing stems. Place the leaves in a sieve, and pour 2-3 cups of water that has been brought to a boil and cooled for 1 minute over the kale. Drain. To speed up the draining process, roll up the kale in a clean dishtowel for a few minutes.
