Here is one quick idea that is easy to implement and barely costs anything in extra food prep. Offer your guests a choice of a twice stuffed Idaho Baked Potato (you can even re-purpose the previous meal periods baked potatoes) with either a house salad or soup. Twice stuffed potatoes are easy to make: hollow out a potato, mix the ingredients with sour cream and chives (maybe even shredded cheese), and re-fill. Then bake in a 350° F oven for 10-15 minutes.
