Semi pot luck with Mother's side of the family tomorrow afternoon.  The part I know about will be fresh smoked ham and pecan pie cups (1 1/2" pecan pies w/ cream cheese crust).  Immediate family will be doing breakfast Christmas morning with eggs, bacon, biscuits, sausage balls, party mix, & dip.
Dad's side will be Christmas Day evening.  Don't have the faintest idea on the menu there.
