Chicken Roll Ups

We love these, but I don't have a "recipe" i just kind of make it. 
Pound out chicken (thighs, breasts, or whatever you have).  Sprinkle each side with salt, pepper,  garlic and Italian seasoning, then layer salami, provolone, spinach and sun dried tomatoes. (Or another seasoning and filling combination of your choice.)
Roll it up, or fold in half.  Secure it with a toothpick.
Heat a cast iron pan (or other oven safe pan) with some olive oil and sear on each side.  Then bake in the oven until cooked through. 

Some other versions we've done are:
Ham thinly sliced or finely chopped with swiss cheese and spinach served with a honey mustard or dijon/mayo dipping sauce.
Bacon, pesto and mozzarella.
Salami, provolone, basil, roasted red peppers, pepperocini peppers and artichoke hearts.

I normally use whatever needs to get used up from the fridge!  What filling will you try?
