I have a couple of excellent recipes for you to try. A hash brown casserole - one pan will feed 20 people easily and another is the 7 layer salad. My recipe is great. Another thing would be to ask people to bring side dishes and you will provide the main dish and beverages. People usually don't mind doing that (I had that done at my 40th b'day and it was wonderful trying all the different dishes!) Email me if you want the recipes and have fun!
