Finely cut the mushrooms, crown broccoli and tofu into small pieces and place in a large bowl.
Add oil, salt and pepper. Mix well.
Prepare wonton and wrap wonton one by one. Heat a large pot of water to a boiling and cook the wontons for 3-4 minutes over medium fire.
Add light soy sauce, dried nori, spring onions, garlic and sesame oil. Scoop around 1 cup of the water for cooking the wontons. Transfer wontons in individual serving bowls.
Garnish some chopped green onions and serve hot.
Notes
I recommend a mild taste for this wonton soup. But if you love a spicy version, add some vinegar and chili oil in serving bowls.
