1. Preheat your oven to 375°F. This will help crisp up the bread and melt the cheese slightly, enhancing the sandwich’s texture and flavor.
2. Slice the Italian loaf or baguette lengthwise, but don’t cut it all the way through. This creates a pocket to hold all the delicious fillings.
3. In a small bowl, whisk together the olive oil, red wine vinegar, Italian seasoning, salt, and pepper. This dressing will add a zesty kick that ties everything together.
4. Brush the inside of the bread with the dressing, ensuring an even coating for maximum flavor.
5. Layer the salami, capicola, mortadella, and provolone cheese inside the bread. I like to alternate the meats and cheese to ensure every bite is balanced.
6. Add the shredded lettuce, tomato slices, red onion, and pepperoncini on top of the meats and cheese. These fresh ingredients bring a delightful crunch and brightness to the sandwich.
7. Wrap the sandwich in aluminum foil and place it in the oven for about 10 minutes, or until the cheese starts to melt. This step is optional but enhances the flavors and melds the ingredients beautifully.
8. Remove from the oven, slice into portions, and serve warm or at room temperature.

When I first tried this technique of warming the sandwich, it reminded me of the way my grandmother would toast our tortas, filling the kitchen with mouthwatering aromas that signaled a meal made with love.
