need a good substitute for white flour in a soup recipe

I almost always have a couple of cooked baked potatoes in my fridge for times like this. Take half the already cooked potato (with or without skin) and blend it with some chicken broth or water in the blender. You can also use regular red or Yukon gold potatoes, it doesn't matter. Just make sure they are cooked first. Blend to the thickness you like and pour into the soup fixings.

Thanks Melissa!  I will try that.  I appreciate the suggestion.
