1. In a large heavy bottomed saucepan over medium heat melt margarine. Add prepared leeks and cook until soft. Add potatoes and continue cooking for about 5 minutes, stir occasionally.
2. Add vegetable broth and pepper. Broth should just cover potato mixture. Add more broth if necessary. Cover and simmer for about 25 minutes until potatoes are well done.
3. Add Sensational Soy beverage.
4. Using a hand-held blender, or in batches in a food processor or blender process soup until smooth. Adjust seasonings and serve immediately. Garnish with snipped fresh chives if desired.

Customize the recipe:

1. Allow soup to cool completely and serve cold (also called Vichyssoise) if desired. Garnish with snipped fresh chives.
2. Recipe easily doubled or halved.
3. Replace margarine with butter.
