To prepare dashi, place water and kombu in a pot. Cover and bring to a boil. Turn off heat, add bonito flakes, stir, cover and allow to sit for 5 to 10 minutes. Strain the dashi to remove the kombu and bonito flakes and discard.
Place dashi back in the pot, add the onions, wakame and carrots. Simmer for 5 minutes over a medium-low flame. Puree the miso with a small amount of the dashi. Reduce the flame to low. Add the miso, Chinese cabbage and tofu. Simmer, without boiling for 2 minutes. Serve and garnish with green onions.
Shiitake mushrooms may be used in place of bonito flakes to season the dashi. Simply place 6 to 8 Eden Shiitake Mushrooms in the dashi water and cook with the kombu 5 minutes. Remove kombu and shiitake. Remove shiitake stems and discard. Discard kombu or use in another dish. Slice the caps thin and place back in the dashi before adding the vegetables.
