Ingredients For Grilled Italian Sausage Sandwich
Italian sausage: These sausages are seasoned with a blend of herbs and spices, giving them a distinctive flavor that pairs perfectly with the other ingredients.
Hoagie rolls: These long, soft rolls are ideal for holding the sausage and toppings, providing a sturdy yet tender base for the sandwich.
Bell peppers: Sliced bell peppers add a sweet and slightly crunchy element to the sandwich, balancing the richness of the sausage.
Onions: Sliced onions, when sautéed, become sweet and caramelized, adding depth to the sandwich's flavor profile.

Toasting the hoagie rolls on the grill adds a delightful crunch and enhances the overall texture of the sandwich.

- Store the sliced bell peppers and sliced onions separately in an airtight container. This keeps them fresh and prevents them from becoming mushy.
