1-First Step: Preheat and prep the rolls Start by preheating your oven to 350°F. This temperature is just right for warming the bread, melting the cheese, and keeping the meats juicy without drying them out. While the oven heats, arrange the 6 sandwich rolls sliced-side up in a 9×13-inch baking dish. Bake the rolls for 5 minutes first. This quick first bake helps the inside get a little warm and the outside get lightly toasted. That small step makes a big difference because it keeps the bottom from getting soggy once the fillings go in.

2-Second Step: Layer the deli meats Remove the rolls from the oven and build each sandwich while the bread is still warm. Fold and place 2 to 3 slices deli ham per roll. Then add 2 to 3 slices Genoa salami per roll, followed by 2 to 3 slices mortadella per roll. The goal is to create a stacked, even layer of meat in each sandwich. If I’m being honest, this is the part that makes the kitchen smell amazing right away. The mix of salty ham, rich mortadella, and bold salami gives these sandwiches their signature deli flavor. Keep the slices slightly folded so they sit neatly and do not slide out when the cheese melts.

3-Third Step: Add the peppers and cheese Top the meat layers with the 1 cup sliced banana peppers. They add a little tang and brightness, which helps balance the richness of the meat and cheese. Then thinly spread the 1/2 red onion slices over the top if you want a bit more bite and crunch. Next, break each of the 6 provolone slices in half and place the pieces on top of the fillings. Using half slices helps the cheese cover the sandwiches more evenly. Provolone melts beautifully and ties all the savory flavors together.

4-Fourth Step: Bake until hot and melty Return the baking dish to the oven and bake for 20 minutes. During this time, the rolls become crisp, the meats heat through, and the provolone melts into a soft, creamy layer on top. Keep an eye on the sandwiches near the end so the bread does not get too dark. This is also the best moment to get your serving toppings ready. Set out the Italian dressing, shredded iceberg lettuce, pepperoncinis, and sliced tomatoes so everyone can build their own sandwich the way they like it.

5-Final Step: Serve hot with your favorite toppings Once the sandwiches come out of the oven, let them rest for a minute or two so the cheese settles a little. Then serve them hot with a drizzle of Italian dressing and the toppings you like most. A few people love extra pepperoncinis for more tang, while others pile on lettuce and tomatoes for freshness.
