Just off the top of my head.. First I would suggest that you have some vegie burgers on hand in case there are any vegetarians in the group. I think they might also like macaroni and cheese or macaroni salad. The girls would probably appreciate tossed salad and/or the raw broccoli salad with bacon and raisins. If you want something Asian, one of the cold noodle salads would be another suggestion. College kids also really miss home baked cookies so I bet they would love chocolate chip cookies,brownies, oatmeal and raisin and/or peanut butter cookies. For appetizers, I would suggest a veggie and dip tray or platter and any Mexican appetizer. The Mexican 7 layer dip can be mostly made a day before and they "scarf" that up really fast. Chili con Queso would be another you might use. I'll continus to think about this and if I come up with some other ideas, I'll post them. Good luck. I know that it will be a lot of fun for you, too:-)!!
