1 can (14-1/2 ounces) reduced-sodium chicken broth
1/2 teaspoon garlic powder
1/4 teaspoon pepper
1/8 teaspoon salt
Sour cream, optional
In a large saucepan, saute onion in butter until tender. Add the broccoli, broth, garlic powder, pepper and salt. Bring to a boil. Reduce heat; cover and simmer until broccoli is tender, 10-12 minutes. Cool slightly.
In a blender, cover and process soup until smooth. Return to the pan and heat through. Garnish servings with sour cream if desired.
