A prosciutto hoagie is a hearty Italian-style sandwich featuring a robust combination of thinly sliced prosciutto, ham, and salami, layered on a hoagie roll. Crisp green leaf lettuce adds a fresh, crunchy texture, while provolone cheese brings a creamy, slightly sharp richness. This bold mix of cured meats, fresh lettuce, and tangy cheese creates a satisfying, deli-style hoagie perfect for a flavorful meal.
