1 can (14-1/2 ounces) reduced-sodium chicken broth
2 tablespoons cornstarch
1 can (12 ounces) fat-free evaporated milk
In a large saucepan, combine the broccoli, onion and broth; simmer for 10-15 minutes or until vegetables are tender. Puree half of the mixture in a blender; return to the saucepan.
In a small bowl, combine cornstarch and 3 tablespoons of milk until smooth. Gradually add remaining milk. Stir into the broccoli mixture. Bring to a boil; boil and stir for 2 minutes or until thickened.
