Vietnamese style noodle soup from 1000 vegan recipes

As promised here is the recipe from 1000 vegan recipes, we made quite a few adjustments to make it gluten free:

1 tablespoon canola oil
1 onion, chopped
1 serrano or hot green chilli, seeded and chopped (we used dried chilli flakes)
1 tablespoon of ginger, chopped
3 tablespoons soy sauce (we used tamari)
2 whole star anise (I couldn't find star anise at the supermarket so left it out)
5 cups of vegetable stock
2 tablespoons of barley miso paste (we used white miso paste without barley so it was g/f)
2 tablespoons hoisin sauce
1 tablespoon fresh lime
1/2 cup hot water
4 ounces (113 grams) dried rice noodles
6 ounces (170 grams) dried seitan (we used smoked tofu but like Batgirl's idea of using fried tofu)
1/2 cup fresh bean sprouts (we left this out since apparently you used eat bean sprouts when taking traditional Chinese medicine)
3 green onions chopped for garnish
1/4 cup chopped coriander for garnish

1. In a large soup pot, heat oil over medium heat. Add onion, cover and cook until softened, 5 minutes. Add the chilli and ginger and cook unitl fragrant. Stir in the soy sauce, anise and broth. Simmer, uncovered for 45 minutes to allow flavours to blend. Strain the soup and return it to the pot discarding the solids. (Toby skipped the straining stage)
2. In a small bowl combine miso, hoisin, lime juice and water and add to the soup, stir in the noodles and the seitan. Cook until the noodles are soft about 10 minutes.
3. Ladle the soup into 4 bowls and garnish with bean sprouts, green onions and cilantro.

Enjoy!
