Well, I've got a sophisticated version. I can't afford to make them for a party, but they make a great on-the-go lunch! And best of all, they're gluten free (if you use corn tortillas).
thin sliced salami or prosciutto
chevre or other desired spreadable cheese
If you're eating right away, briefly heat the tortillas. (I did 15s in the microwave). Spread the chevre on the tortilla. Layer with salami, then top with arugula. Roll up, and eat. You can slice them if you want, but mine didn't last that long.
