Get the recipe for Italian tuna salad sandwiches featuring provolone cheese, marinated artichoke hearts, roasted red peppers and more.
In a large bowl, combine tuna and oil, salt, pepper, onions, celery, chopped artichoke hearts and liquid, roasted red peppers and liquid, capers, Calabrian chiles, oregano, lemon zest and juice. Taste to adjust seasoning and set aside.
In a griddle or large heavy skillet set over medium-high heat, add olive oil. Split the roll in half and place face down in the hot oil for 1 minute until the bread is toasted. Remove the roll and place face-up on your work surface. Repeat with the rest of the rolls. Reduce the heat to low while you assemble sandwiches.
In a small bowl, combine the shredded mozzarella and Parmesan.
Spread 2 tablespoons of pesto on each half of each toasted sandwich roll. Add a slice of provolone to all 4 bottom pieces of bread, then top with 3 to 4 generous scoops of the tuna salad. Add 2 tablespoons of the cheese mixture on top, then a final slice of provolone. Close the sandwiches.
Increase the heat on the griddle to high and add a generous drizzle of olive oil. Working with one or two sandwiches at a time, place them in the hot oil and use a smaller heavy cast iron skillet or pot lid to press down. Cook for 1 to 2 minutes until toasted, then remove the lid, flip the sandwich and press down again. Reduce the heat to medium-low and cook until the bread is toasted, the tuna salad is heated through and the cheese is fully melted, 3 to 4 minutes. Remove from heat, cut in half and serve immediately.
