Preheat a stove or griddle over medium-high heat.

Coat the griddle with oil or cooking spray to prevent sticking.

Unpack the Italian sausages and slice them lengthwise, partially splitting them, leaving them connected.

Place the sausages split-side down on the preheated griddle.

In a frying pan or skillet, heat a drizzle of oil over medium heat.

Thinly slice the green peppers and onions into rings.

Add the sliced peppers and onions to the skillet when the oil is hot.

Grill the sausages for about 10 minutes, flipping halfway through, until fully cooked and browned.

After 5 minutes, flip the sausage over to cook the other side.

Add a pinch of black pepper, paprika, and seasoned salt to the peppers and onions and stir until they soften and wilt down.

Slice the hero rolls and spread mayonnaise on both sides.

Toast the hero rolls on the griddle until golden brown on both sides.

Split the sausage portion into 2 and place it inside the toasted hero roll.

Add your preferred sauce (ketchup, mustard, buffalo, bbq, etc.) to the sandwich.

Add a portion of the sauteed vegetables to the sandwich.

Serve and enjoy!
