If a Philly cheesesteak and a classic sausage-and-peppers hoagie had a loud, delicious weeknight baby, it would be this sheet-pan situation. We are not chopping the meat into a minced griddle pile here. This is a hoagie build: juicy Italian sausage links, peppers and onions roasted hot enough to get crisp edges, then everything gets tucked into warm torpedo rolls with provolone and whatever heat level you are feeling.
The goal is char without steaming. That means a big pan, high heat, and spacing things out like you actually want them to brown. I also use a simple little de-fatting trick at the end so the sandwich tastes rich, not greasy. It is low drama, high reward, and the leftovers reheat like champs.
