Ask what you can bring. If you aren't asked to bring anything,
think about:

something for breakfast -- special coffee, maple syrup, stone ground
grits, hot chocolate

something that would work for movie/football nibbles, a relish tray,
or sides for turkey sandwiches -- olives, roasted red peppers, dried
fruit, pimento cheese, good crackers, interesting pickles (cucumber,
veggie, onions, garlic), cheese straws, cheese, celery, popcorn and
seasonings, nuts, hummus, edamame
