any smoked cheese, shrimp, oysters, smoked meatloaf, smoked hotdogs, smoked pork steaks, smoked bologna, stuffed peppers & jalapeno's. Most of these are "finger foods" that I smoke while doing a "long" or over night smoke.
Cold Smoked butter is great on a cooked steak. There are a lot more but this is just a few that came to mind.
My rule is, If you can eat it you can smoke it!
