Place all ingredients into a food processor. Process until mixture becomes spreadable, scrape down the sides as needed.
For the muffaletta
Slice bread in half, scoop out excess bread until there is 1/2 inch to 1 inch of the bread left. Generously spread the olive salad onto both sides of the bread. Layer the meats and cheese. Top with the top half of the bread. Tightly wrap the sandwich in plastic wrap. This will take a few times wrapping it with the plastic wrap around the entire sandwich.
Place the sandwich in the fridge and put something heavy on top so the top of the bread squishes down. Leave overnight, slice into 4 pieces and serve.
