Canapes

Canapes are individual appetizers or interruptions.
Here are some ideas. The one thing they tend to have in common is that the toppings are smaller than the fillings, which is what "canape" means.

A general approach:
Stuff Athens Phyllo Cups
If you use these, bake them at 350F on a baking sheet for 3-4 minutes to crisp, let cool, stuff, then rebake for about 5 minutes if hot. The broiler might be best.

Some ideas:
Hot:

Provolone, sliced good turkey, and a small ball of pesto
Brie and Bacon
Smoked Ham and Swiss
Taco meat and cheddar
Pulled pork and cheddar (optionally cole slaw)
Beefaroni with shredded mozzarella
Mini-Ruebens
Mini-missing 3/4: rare roast beef, cheddar, one drop of garlic butter

Cold:

Cream Cheese, Lox, a caper or two, optionally minced red onion
Karoun Caraway String cheese and pesto
