Wash all the veggies and then chop into chunks according to ingredients list
Add all the veggies to a large pot, then add in the ginger, bay leaves, coriander seeds, salt and pepper and olive oil
Cover with 2 litres of filtered water
On a high heat bring the soup to the boil and then reduce heat to low, and simmer for approximately 2 hours
Once reduced and you're happy with the flavour, remove the soup from the heat
Place a colander over a large bowl, then carefully pour the soup into the colander so all the liquid drains out into the bowl.
With the left over liquid you should have around 3 cups, you can then separate into smaller quantities and freeze to use for stock. Or you can serve a cup of broth with some miso, shallots and tofu, and a splash of Tamari.
