I had to put this recipe on here because its too delicious (plus cheap and easy) not to share.
2 veg oxos (but any veg stock should be fine)
Put all in a large stock pot with enough water to cover and cook until veg is soft, then blend.
Once blended add some chilli (flakes or in oil) to taste, and salt and pepper
Pour in half a pot of cream, et voila.
BE WARNED: This makes rather a lot of soup, so make sure to have some tupperware on hand (Ive started using empty plastic milk bottles to store soup, and they work a treat).
