Instructions

  1. Add all of the vegetables, stock, water and bay leaves to a large pot and bring to the boil.
  2. Reduce the heat and simmer until the vegetables are quite soft.
  3. Allow the vegetables to cool a little then puree in a food processor in batches until smooth. (Added January 2007: Include 2 cups of the cooking liquid reserving the rest to adjust the thickness later.).
  4. Return to the heat and stir in the pepper and soy sauce or salt.
  5. If using, stir in the yogurt taking care to not let the soup boil. (Added January 2007: If the soup is too thick for your taste, stir in a bit of the reserved cooking liquid.).
  6. Serve sprinkled with chopped chives.
