We do a casual, "cold cuts" dinner every Christmas Eve (although I make scalloped potatoes as well). We've done it on occasion at other times of the year, too, and we really enjoy it.
Crackers, French bread, corned beef, ham, roast beef (obviously you get whatever you like)...various cheeses (usually Havarti and cheddar) cut up...some crackers...some black olives.
I lay all the meats out on a platter in a circle with the olives in the center, slice the cheeses and set them out in the center of another plate surrounded by bread slices and crackers, then sometimes get a nice pate too or some dips (like hummus or ranch dressing.) My Mom used to cut up celery with peanut butter, hubby prefers celery with cream cheese. I hate celery but I do it for him on Xmas.
Then we sit in the living room with heaping plates and eat. There's ususally plenty of leftovers, too, and this is always fun. It feels special, even though it's just cold cuts! We graze all night.
