I'm sure this is a food forum faux pas, but I would put out a platter of mini quiches from Trader Joe's or Costco. People love that stuff. As well as the crème puffs that you can just defrost from Safeway or giant. I find them delightful with a glass of champagne. Just put them on a platter and put the boxes in the outside trash
I love the homemade ideas posted above, I'm just suggesting these as easy additions.
