We generally contribute to at least three different meals during the Christmas week -- my family, DH's family and church. I take the same food items to all three and it cuts down on the prep work, shopping time, and cooking time.
This year I bought one large spiral ham when it went on sale and had plenty to cover all three occasions. Same with side dishes and desserts. I stocked up on dinner rolls a few weeks ago and froze them until they were needed for each event.
