Cut the loaf in half horizontally. Spread the Olive Giardiniera Salad crust to crust on both sides of the bread. Then, layer the cheese on the bottom, followed by high ribbons of the mortadella, salami and capicola. Cover with the top half of the bread and let sit 20 to 30 minutes so the salad's oil can soak into the bread. Cut into pie-shaped wedges and serve to the masses.
Put the olives, red peppers, giardiniera with oil, capers, vinegar, parsley and sugar in the bowl of a food processor and pulse 8 to 10 times until a coarse relish forms.
