Courgette Leek and Potato Soup

I made this soup yesterday using courgettes and potatoes from the veg patch.  Quite satisfying to know how fresh it was, about 20 steps from patch to pot!

Ingredients
3 courgettes, thickly sliced
1 large leek, cleaned and sliced
3 medium sized potatoes, peeled and cubed
2 tbsp sunflower oil
800mls veg stock
White pepper to taste
A small bunch of parsley, finely chopped
A teasp dried mixed dried herbs
100 mls single cream.

Method
Heat the oil in a pan and add the courgettes and leeks cooking until softened.  Then add the potatoes, herbs and stock.  Simmer for 10 minutes or until the potato is soft.  Season with the white pepper to taste.  I don't add salt as the stock tends to have salt in it already.
Blitz the vegetables using a stick blender until smooth and stir though the cream.
Sprinkle with the parsley and serve with a lovely crusty cob.
