An Italian cold cut sub stacked with salami, capicola, and provolone is a protein-packed deli classic. This family-sized sandwich is loaded with bold Italian-American flavors.
Lay the Italian sub roll flat on a large cutting board and slice it horizontally, keeping one side attached to create a hinge.
Drizzle the inside of both halves with olive oil and red wine vinegar, ensuring even moisture for every bite.
Layer the slices of salami, capicola, and provolone cheese evenly across the bottom half, slightly folding the meats for texture.
Top with shredded iceberg lettuce, tomato slices, and thinly sliced red onion, distributing the vegetables all the way to the edges.
Sprinkle dried oregano, kosher salt, and freshly ground black pepper generously over the vegetables, then add pepperoncini for zing.
Carefully close the sandwich, pressing firmly to compact the layers, then slice crosswise into 4 large pieces.
Serve immediately to keep the bread crisp and the vegetables fresh.
