Salt and freshly ground pepper
1 3/4 pounds medium asparagus, tips cut to 1 inch, stems chopped
3 cups spinach (3 1/2 ounces)
4 teaspoons nonfat plain yogurt
Edible flowers, for garnish (optional)
Heat the olive oil in a medium saucepan. Add the leeks and cook over moderately low heat, stirring often, until softened, about 6 minutes. Add the stock, season with salt and pepper and bring to a boil. Add the asparagus stems and cook over moderately low heat until tender, about 6 minutes. Add the spinach and cook for 3 minutes.
Puree the soup in a blender. Refrigerate until chilled, at least 2 hours or overnight. Season with salt and pepper.
