Heat the olive oil in a pot over medium heat; add the onions, chillies, garlic and ginger and sauté, 2 minutes. Stir in the star anise, miso paste, rice vinegar, soy sauce, hoisin sauce and vegetable stock. Simmer the broth for 5 minutes.
Add the cooked Quorn Pieces, rice noodles and cook, 2 minutes. Add the mushrooms and pak choy and simmer, 1 minute. Stir in the edamame beans, bean sprouts, sugar snaps, spring onions and cilantro.
Spoon the soup into serving bowls and scatter the mint leaves on top.
The rice noodles can easily be replaced with other vegan noodle alternatives such as udon or hokkien noodles, if preferred. Exotic mushrooms such as shiitake, shimeji and oyster mushrooms are perfect for this soup.
