here are 2. 1 super easy and 1 that takes a little more time. Both very good and you can use your rig to add some smoky flavor if you like
1) The Easy: get a baguette and slice thin, got get a boar's head panino (which is mozzerella or prevelone wrapped around salami. some have arugula in there too- they are all very good). SLice that thin and cook on a pizza stone until melted. A little smoke on these is very good. Finish with fresh basil and salt and fresh cracked pepper. They will be gone in minutes.
2) A little more work but worth it: smoke a duck breast to med rare and slice it in matchsticks. take a baguette, slice thin, add a schmear of brie, then add a little dollop of fig jam, then pile on the duck on top with caramelized red onion. These are like crack:
These are very good (if not better) served cold so they are good for a party liek this.
