We usually eat the big meal around 4 or 4:30 (still leaves time in the evening to grab another piece of pie or a turkey sandwich). My kids are 6 and 3, and they would revolt if no lunch was served. So we do a collection of appetizers for lunch--usually around 11:30. Roasted shrimp cocktail, cheese plate, some sort of hot dip, cut up vegetables, etc. That said, our Thanksgiving is small, just the 4 of us plus my parents so it's not a lot of trouble to make a few small appetizers for everyone to share. Would obviously be more labor intensive if you were serving a big crowd.
