We do this too and here's some things we have had:
Staples every year:
Mini Ham Biscuits (hey, we're Southern! cut refrigerated biscuits in 1/4s and cook, slice and add small pieces of ham...I usually fry it in a little butter...I know, very Southern!)
BBQ Hotdogs (like cocktail weiners but better and cheaper...I use whatever hotdogs are on sale, cut into bit sized pieces, add BBQ sauce of your choice!...cook on stove till they start to get "fat"...haha)
Chocolate Dipped Pecans...take pecan halves (salted, thank you)...dip in almond bark or chocolate about 1/2 way...let harden on wax paper
Whiskey Sour Punch...a can a frozen limeade thawed, a can of frozen orange-type juice thawed, use one of the empty cans and measure 1 1/2 cans of lemon juice (I use bottled), 2 cans of whiskey, 2 lt spite/7up/gingerale (your choice)...I usually float an ice ring that I make of marachino cherries and water in my bundt cake pan ahead of time...looks pretty and when it melts, cherries are good in the drinks! Yummy!
There are other things we have, but these are the ones I haven't seen mentioned here!
