Add all the vegetables to a soup kettle or large pan. Add the tinned tomatoes then use the tin to add 2 tin’s worth of water. Add the rest of the ingredients.
If using a soup kettle set to purée programme and start.
If using a saucepan, bring to the boil then turn down the heat and simmer until everything is cooked through. Blend using a hand blender or liquidiser.
If the soup is too thick add water to desired consistency. Taste and adjust seasoning if necessary.
