In a small bowl mix together the butter and the fresh Italian parsley, set aside.
In small dish mix together bread crumbs and parmesan cheese, set aside.
Tenderize the 4 slices of chicken. (this is done using a meat tenderizer, banging on the meat 4-5 times on both sides). Lay out the 4 slices of chicken, sprinkle with salt (only if using the cooked ham and not the prosciutto) spread the butter, parsley mixture on the slices, top with 1 slice of ham or prosciutto and a slice of cheese (2 slices if necessary), roll up and secure with a toothpick or 2.
Then roll each one in the bread crumb & parmesan cheese mixture and place in the prepared baking pan. Sprinkle any left over crumb mixture on top of the roll-ups. Sprinkle with a pinch or two of salt and drizzle with a little olive oil or a little butter. Bake for about 30-35 minutes. Serve immediately. Enjoy!
