This is how I would modify it next time:
Asparagus Soup
I cup chopped onion
6 green onions, sliced
3 tablespoons butter
1 ½ cups fresh mushrooms, chopped
1 pound fresh asparagus, trimmed and cut into ½ inch pieces
2 (14.5 oz.) cans chicken broth
½ teaspoon salt
½ teaspoon thyme
¼ teaspoon pepper
1/8 teaspoon cayenne pepper
3 cups cooked wild rice
2 tablespoons cornstarch
¼ cup cold water
In a 3-qt. saucepan, sauté onions in butter for 4 minutes. Add mushrooms and cook until tender. Add asparagus, broth and seasonings; cover and simmer for 30 minutes.
Add rice. Combine cornstarch and water until smooth; gradually stir into soup. Bring to a boil; cook and stir for 2 minutes or until thickened. 4-6 servings
