A quick to prepare, low-fat and delicious soup adapted from a recipe in the July 2008 issue of the 'Australian Table' magazine. Not as green as its recipe sibling - Recipe #135165 - this is basically a pea-ified version (if I can be allowed to coin that word) of a classic potato and leek soup, which is what drew me to the recipe. Potato and leek soups have always been a favourite of mine, one of those really safe, classic, always delicious combinations, and always SO much better if a home-made stock is used. The original version of this recipe specified 5 minutes preparation time. Such times are clearly determined on the assumption that all the ingredients are magically ready to go. My guess is that it would take me 5 minutes just to wash and chop the leeks, so I've increased the preparation time to 10 minutes. That still makes this a quick to prepare recipe. For a vegetarian version use a vegetable stock, such as my Recipe #135453 which makes productive use of all your vegetable peelings, and omit the prosciutto.
