I often change the type of meat I put in - sometimes veal cutlets, sometimes roasted pork, chicken, or turkey breasts. I add mayo or mustard, cheese (swiss or some kind of portuguese), sweet pickles, and olive oil bathed sundried tomatoes (I let them stand on a bowl with olive oil for a bit before putting in the sandwich).
I wrap the sandwich well because they can drip, but they are absolutely delicious!
