Swanson's Chicken broth is gluten free...I think the Beef broth is aswell,
although I never buy it.  Another new one, which I recently purchased comes
in a 8 oz. jar and is in paste form...it's made by a company called Superior
Touch and is called "Better Than Bouillon" chicken base.  The ingredient list
on the jar I appears to be gluten free.
