Instructions

Prepare Olive Salad:
In a bowl, combine olives, pickled vegetables, olive oil, red wine vinegar, oregano, and minced garlic. Mix well and set aside.

Slice Bread:
Cut the Italian loaf horizontally in half.

Mix Dressing:
In a small bowl, whisk together olive oil, red wine vinegar, oregano, red pepper flakes, salt, and black pepper.

Assemble Sandwich:
Brush both halves of bread generously with the dressing. Layer salami, ham, mortadella, provolone, and mozzarella evenly on the bottom half. Spread olive salad over the meats and cheeses.

Finish Sandwich:
Place the top half of the bread over the filling and press down gently.

Serve:
Wrap the sandwich tightly in plastic wrap and refrigerate for at least 1 hour to allow flavors to meld. Slice into wedges and serve cold or at room temperature.
