Place a sheet of plastic wrap on the counter and arrange the salami slices in overlapping rows so that they form one solid sheet.
Spread the cream cheese over the entire bed of salami and sprinkle the 3 toppings — pepper, parsley, olives — each over a third of the salami.
Using the plastic wrap, roll the salami slices together tightly and then refrigerate for 2 hours. Then remove the plastic wrap and cut the roll into individual portions with a sharp knife.
