Step 1

Heat a soup pot over medium heat. Add the olive oil, and followed by the ginger. Cook for 30 seconds, then add the tomato chunks. Cook for a few minutes until the tomatoes are softened around the edges.

Step 2

Now stir in mushrooms, and cook for another 2-3 minutes. Then add the water, silken tofu, dried seaweed, light soy sauce and white pepper powder. Cover, bring to a boil, and simmer for 3 minutes over medium heat.

Step 3

Finally, stir in the black vinegar, sesame oil, baby spinach, and salt to taste. When the soup has come back up to a boil and the spinach has wilted down, top with the scallions and/or cilantro and serve.
