We have had lasange for Christmas Dinner, Clam Chowder also. Some friends of mine have a foreign Christmas each year, making food and decorations, and learning the holiday customs from the
country they're using (different each year)
How about having an appetizer buffet? You could have sandwich makings and
cocktail size buns, appitizer meatballs or mini riblets, a couple of salads or vegtable platters, all kinds of good stuff (how about stuffed celery?)
