My grandmother was a Tupperware dealer in the late 50's, for about 15 years. (yes, I still have a houseful). But I do remember a chicken soup she made for many years after that. And it was good. I contacted Tupperware and they sent me the link to a Chicken Soup recipe, but it has orzo, the little pasta that looks like rice. It's also not made like grandma made it, but the product used now, wasn't even thought of then. I hope it may be close to one you are looking for:
