I found this recipe at Pinchin Your Pennies. I got it from a fellow couponer on . She got it from Tightwad Gazzette. The Goodie is optional as it is useually more expensive. I love this recipe as there are many different casseroles you can make. My family really enjoys this recipe. I find that it is best to preboil the potatoes till fork tender before using them. As for the binder I've used sour cream and creamed soups together before with great success as the casserole is creamy and not dry.
