A delightful twist on the classic Italian sausage sandwich, perfect for a quick and satisfying meal.
Preheat your oven to 375°F.
Preheating ensures even cooking and optimal texture.
In a skillet, cook the Italian sausage over medium heat until browned.
Break the sausage into small pieces for even cooking.
Add the chopped red onion, bell pepper, and olives to the skillet. Cook until the vegetables are tender.
Stir occasionally to prevent sticking and ensure even cooking.
Slice the sub rolls lengthwise, being careful not to cut all the way through.
Hollow out the rolls slightly to make room for the filling.
Fill each roll with the sausage and vegetable mixture, then top with shredded mozzarella cheese.
Press the filling gently to ensure it stays in place.
Wrap each sandwich in aluminum foil and place on a baking sheet.
Wrapping in foil helps to keep the sandwiches moist and warm.
Bake the sandwiches in the preheated oven for about 15 minutes, or until the cheese is melted.
Check the sandwiches halfway through to ensure even heating.
Carefully unwrap the sandwiches and serve warm.
Serve with a side of marinara sauce for dipping.
