Place the olives, canned roasted bell peppers and drained giardiniera (pickled cauliflower, carrots, celery and peppers) in a food processor fitted with a stainless steel cutting blade and process until everything is finely chopped. If not using a food processor, chop finely with a knife. Move this mixture to a large bowl.
Using a knife, chop provolone cheese in squares (if you bought it as slices) or cubes if you bought it as a cheese block. Chop salami with a knife as well. Add salami and provolone cheese to the bowl with the other ingredients.
