Ingredients

2 tsp olive oil

1 1/2 pounds asparagus, cut into 2 inch pieces

1 medium onion, chopped

1 celery stalk, chopped

2 leeks, chopped (white part only)

1 medium potato, peeled and cut into 1 inch pieces

3 1/2 cups fat-free reduced sodium chicken broth

1/2 cup fat-free sour cream

Preparation

Heat oil in a large Dutch oven. Add asparagus, onion, celery, leeks and potato, and cook for 5 minutes, stirring occasionally. Add broth and simmer for 20 minutes, until vegetables are softened. Transfer soup to a blender and puree until smooth.

You may need to do this in two stages. Return soup to Dutch oven, add sour cream and stir on low heat until blended.
