Cream of Asparagus Soup

This is the perfect thing to make with the Costco-size asparagus after you've grilled it, made pizza with it, etc.and you don't want the rest to go to waste!

1/4 cup butter ( I use ½ butter and ½ olive oil)

 1 onion, chopped

 3 stalks celery, chopped

 3 tablespoons all-purpose flour

 6 cups chicken broth

1 potato, peeled and diced

 1 pound fresh asparagus, trimmed and coarsely chopped

 3/4 cup half-and-half ( I used milk)

 1 tablespoon soy sauce

 1/4 teaspoon ground black pepper

 1/4 teaspoon ground white pepper

Sauté onions and celery in butter until very soft. Sprinkle flour over vegetables and stir to coat. Cook for 1-2 minutes. Add chicken broth and bring to a simmer. Add vegetables and cook for 10-12 minutes until they are tender. Puree. Add half and half and seasonings. Heat until very hot but not boiling. Serve with rustic bread and salad.
