Preheat the oven to 350°F and line a baking sheet with parchment paper.
Place the hoagie buns onto the prepared baking sheet and top with chopped rosemary and grated Parmesan cheese.
2 hoagie rolls, 1 Tbsp fresh or dried rosemary, finely chopped, 1/4 cup parmesan cheese, shredded
Bake at 350℉ for 5-6 minutes or until the Parmesan cheese is melted and the bread is lightly toasted. (If the hoagie buns are not pre-sliced, carefully cut them in half lengthwise, leaving one side attached so the sandwich stays together.)
Carefully remove the baking sheet from the oven and let the bread cool slightly.
As the bread cools, prepare all the sandwich toppings so everything is ready to assemble.
Open one hoagie bun and spread mayo on both sides. Layer the sliced meats and cheese onto the bottom half of the bun. Repeat with the second hoagie bun, divide the meat and cheese evenly between both sandwiches.
