A large deli-pasta salad is always good, and you can use cherry tomatoes, green pepper and black olives to garnish in holiday colors. Just use shell macaroni, Italian dressing, cubed cheeses and salami, artichoke hearts and mushrooms, etc. You can certainly always leave the meat out for a vegetarian version. Another nice one is spinach, bacon, onion and pomegranate with a pom vinaigrette; or if you want to go with something a little heartier, what about wings or calzone in wedges?
I discovered that if you make popovers in mini-muffin tins, because they are small they don't present that soggy texture if they aren't eaten on the spot. I roll a thin ribbon of ham around a small cube of cheese and place it like a column into the batter, which is made with eggnog rather than milk. They are very tasty.
