If you're heading to the supermarket, make sure to pick up fresh Italian sausages, which are the star of this dish. Hoagie rolls might not be a pantry staple, so grab those as well.

Technique Tip for This Recipe
To enhance the flavor of the italian sausages, consider pricking them with a fork before grilling. This allows the juices to escape and prevents the sausages from bursting.

This adds a subtle, smoky flavor that complements the marinara sauce and shredded mozzarella cheese.

How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Wrap each sandwich in aluminum foil to keep it moist. Place the wrapped sandwiches on a baking sheet and heat for about 15-20 minutes, or until the sausages are warmed through and the cheese is melted.
Stovetop Method: Heat a non-stick skillet over medium heat. Place the sandwich in the skillet and cover with a lid. Cook for about 5-7 minutes on each side, or until the sausages are heated through and the cheese is melted. You can add a splash of water to the skillet and cover it to create steam, which helps in reheating evenly.
Microwave Method: Place the sandwich on a microwave-safe plate. Cover it with a damp paper towel to keep it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating. Be cautious as the bread might get a bit soggy.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the sandwich in the air fryer basket and heat for about 5-7 minutes. This method will keep the bread crispy while ensuring the sausages and cheese are thoroughly warmed.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Wrap the sandwich in aluminum foil and place it in the toaster oven. Heat for about 10-15 minutes, or until the sausages are hot and the cheese is melted. For a crispy bread, unwrap the foil for the last 5 minutes of heating.
