I would go for vol aux vents, mini quiches, sausage rolls, mozarella sticks with dip, mini brie and cranberry sandwiches, mini turkey and cranberry sandwiches, potato wedges with dip, crudite with dip (eg carrot sticks, cucumber sticks, slices of pepper, slices of celery) cherry tomatoes, olives, the 70's classic hedgehog with cheese cubes, pineapple, grapes, etc.
Mince pies, Clootie dumpling if it is done in your neck of the woods, chocolate log, pavlova or mini filled meringues, satsumas etc.
Non of it is very healthy...
