Roquefort gougeres (or their Gorgenzola cousins) are my "go-to" -- hot out of the oven they practically SCREAM for a glass of wine.

One of my seasonal faves, you can form them in muffin tins if you like. Great flavor... http://www.bonappetit.com/recipes/2004/12/pancetta_crisps_with_goat_cheese_and_pear

Bacon wrapped stuffed dates. Perfect blend of salty and sweet. I like to stuff them with bleu cheese, feta or almonds.
