Does anyone know the recipe for Knott's chicken noodle soup?

I'm a big fan of Knott's Chicken Dinner Restaurant, and I usually get the traditional chicken dinner. One of the starter options is a delicious creamy chicken noodle soup. I have tried to find the recipe for it online with no success. I even own the Knott's cookbook but unfortunately the only chicken soup recipe is "Charleston's chicken soup" which is not the same. Does anyone know the recipe or know where to find it? I would love to make it at home some time.
