Skip the chicken all together and follow the remaining recipe to make a perfect vegan soup. Just replace the chicken broth with vegetable broth. If you can find enoki mushroom, they add a great crunch too.
Adjust the corn starch or arrowroot powder, to the textures you prefer.
Adjust green chilies and fresh ginger to take the spice level up or down.
Go ahead and double up on cilantro if you have extra.
