Saute all the veg in a large frying until the onions are tender.
Transfer veg to soup maker or large pan if using and add all the remaining ingredients except the cheese and pistou ingredients.
Set soup makerto chunky or simmer in pan for 20-25 minutes until all the veg is tender.
Once the soup is cooked, ladle out 100ml of soup in to a food processor or blender, avoiding any veg.
Chuck in the rest of the pistou ingredients and blend.
Serve the soup, pour over with the pistou and top with low fat grated cheese and eat. *Side note: If you're making this soup ahead and planning to freeze and warm up later, then don't add the pistou until you're ready to eat as the basil will overcook and lose its flavour. If it does, then add a stock cube and heat it through.
