A delightful and easy-to-make Italian sausage sub recipe, perfect for a hearty meal.
Heat the olive oil in a skillet over medium heat.
Ensure the oil is hot before adding the sausages to prevent sticking.
Brown the Italian sausages on all sides in the skillet.
Turn the sausages frequently to brown them evenly.
Transfer the browned sausages to the slow cooker.
Place the sausages in a single layer for even cooking.
Add the marinara sauce, sliced green peppers, sliced onion, oregano, and basil to the slow cooker.
Stir the ingredients gently to combine them well.
Cover and cook on low for 4 hours.
Check occasionally to ensure the sauce doesn't dry out.
Toast the hoagie rolls if desired.
Toasting adds a nice crunch and prevents the rolls from becoming soggy.
Fill each hoagie roll with a sausage, peppers, onion, and sauce.
Add a generous amount of sauce for extra flavor.
Sprinkle grated parmesan cheese on top before serving.
Serve immediately for the best taste and texture.
