Something a little different that we have done successfully for years is to purchase cold cuts, cheese and breads that we normally eat, with a few extras, and lay out a spread of ingredients to make great sandwiches, with each participant making their own, and using mayo, mustard, salad dressing, olive oil, etc. to dress the bread. That way, you have leftovers only of bread and things that normally go into your fridge anyways. And if there are leftover black olives, or pickles, well they store in the fridge too, and are great for snacking on. No cooking, little clean-up, and everybody is filled with whatever kind of sandwich floats their boat.
How extravagant, or simple it is is totally up to you. As always, hope this helps.
May your hot foods be hot, your cold foods be cold, and your cheddar at room temperature.
