In a food processor, add the olives, pickled vegetables, red pepper, garlic, vinegar, ground black pepper, and Italian seasoning. Pulse until chunky. Don’t over-process.
Cut the loaf in half horizontally.
Remove part of the soft inside of the loaf to make room for the fillings. Save for breadcrumbs or croutons.
Spread the olive mixture on the bottom of the loaf.
Layer each meat and then top with a layer of cheese.
Drizzle the inside of the top of the loaf with good olive oil and season with salt and pepper.
Close up the sandwich and wrap tightly with plastic wrap, then place in the fridge overnight.
