Whisk in the miso paste then add the shitake mushrooms, their soaking water and the noodles. Bring back to the boil and simmer for 5 minutes.
Stir in the prawns and bok choy and cook for another 1-2 minutes until the prawns are just cooked and the bok choy is wilted.
To serve: Ladle the soup into bowls and divide the noodles and prawns between serves. Garnish with the spring onions and coriander.
