This grilled Italian sausage sandwich is a delightful combination of savory flavors and textures. Perfect for a summer cookout or a quick weeknight dinner, it features juicy vegan Italian sausages, crisp bell peppers, and sweet onions, all grilled to perfection and nestled in a toasted hoagie roll.
If you're not familiar with vegan Italian sausages, they can be found in the refrigerated section of most supermarkets, often near other plant-based meat alternatives. Hoagie rolls are a type of long sandwich roll, typically found in the bakery section. Make sure to pick up fresh bell peppers and onions for the best flavor.

Ingredients for Grilled Italian Sausage Sandwich
Vegan italian sausages: Plant-based sausages that mimic the flavor and texture of traditional Italian sausages. Hoagie rolls: Long sandwich rolls that are perfect for holding the sausages and toppings. Bell peppers: Fresh, colorful peppers that add sweetness and crunch. Onions: Sliced onions that caramelize beautifully on the grill. Olive oil: Used to coat the vegetables for grilling. Salt and pepper: Basic seasonings to enhance the flavors of the vegetables.
Technique Tip for This Recipe
When grilling vegan italian sausages, make sure to preheat the grill to medium-high heat to ensure even cooking. To enhance the flavor of the bell peppers and onions, toss them in olive oil with a pinch of salt and pepper before grilling. This will help them caramelize and develop a rich, smoky taste. For the best texture, grill the hoagie rolls for just 1-2 minutes until they are lightly browned and crispy on the outside.

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 heated through and the bread is warm.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil to the pan. Place the sandwich in the skillet and cover with a lid. Heat for about 5-7 minutes on each side, or until the sausages are warmed through and the bread is toasted.
Microwave Method: For a quick reheat, wrap the sandwich in 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 can become soggy if overheated.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the sandwich on a baking tray and heat for about 10-15 minutes, or until the sausages are hot and the bread is crispy.
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 give you a crispy bread and evenly heated sausages.
Grill Method: Preheat your grill to medium heat. Wrap the sandwich in aluminum foil and place it on the grill. Heat for about 10 minutes, turning halfway through, until the sausages are hot and the bread is toasted.
