I've used this recipe for sooo many years. Grandma Webster who babysat us in Gary IN made this for us. Diced potatoes, diced onions, cook until tender, add butter and milk, simmer til warmed through. When you start adding celery, carrots, etc., it's vegetable soup, not potato soup to me. DH not crazy about this soup because there is no "meat" in it. But I love this recipe and it's the one I stick with. I can eat the whole pot by myself no problem.
