Tailgate Tip: Prepare sandwiches the day before the game. Place in zip-top plastic freezer bags, and refrigerate overnight.
Pulse pickled vegetables in food processor 8 to 10 times or until finely chopped. Stir in olives and dressing.
Spread 1 heaping tablespoonful pickled vegetable mixture over cut side of each roll bottom. Top each with 1 Swiss cheese slice half, 1 ham slice, 1 salami slice, 1 provolone cheese slice half, and roll tops. Cover with plastic wrap. Serve immediately, or chill until ready to serve.
Note: We tested with Mezzetta Italian Mix Giardiniera pickled vegetables and Newman's Own Olive Oil & Vinegar dressing.
