We have Christmas Dinner about 3pm with the pudding about 5, so we don’t need a full on meal/buffet in the evening. We always have a cheeseboard with various trimmings as it’s easy and everyone can eat as much or as little as they like. Anyone who wants one can make a turkey sandwich. Crisps, fruit, cake, chocolate openly available. This works well and I’m sure if I suggested a change there would be uproar. However I would like to consider alternative ideas that are simple, light, little prep, help yourself type things? Adult guests only.
