DD has been home 5 minutes from college and already complaining! I need to make her the traditional green bean casserole that has sauce, mushrooms and FF onion rings. Would like to do something a little more Chowish than Campbell's cream of mushroom soup. If you can suggest how to make this non-dairy, even better (soy milk, Fleishman's margarine, chicken soup stock, etc.) Any suggestions? Happy Tgiving!
