Lay the lettuce leaves on a large platter to form a bed. Roll the meats into cigar or funnel shapes. Place all of the items on the platter in an attractive manner, either center to outside or side-by-side. I would use the marinated and pickled items in between the various meats and cheeses. Think of the colors as you separate. The Parmesan cheese curls can be randomly placed on top of the other items. The platter can be prepared several hours ahead and refrigerated until about 30 minutes before serving, then brought to room temperature.
If you prefer to marinade your own vegetables, a basic marinade starts with olive oil to which a little balsamic (or red wine) vinegar, oregano and/or basil, salt and pepper are added. I would also add garlic to the roasted peppers.
