Brown the sausages.
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the Italian sausage links and cook until well-browned on all sides, about 8 to 10 minutes. They do not need to be fully cooked through yet. Transfer sausages to a plate and set aside.
TIPPrick each sausage a few times with a fork to prevent them from bursting in the pan. - saute · ~12 min
Cook the peppers and onions.
1.Add the remaining 1 tablespoon olive oil to the same skillet over medium heat.2.Add the sliced bell peppers and onions. Season with half the salt and black pepper.3.Cook, stirring occasionally, until vegetables are soft and beginning to caramelize, about 10 to 12 minutes.4.Add the minced garlic and cook until fragrant, about 30 seconds.TIPDon't stir too often — letting the vegetables sit undisturbed for a couple of minutes helps them develop a nice char. - simmer · ~10 min

Toast the sub rolls.
While the sausages simmer, preheat the oven to 400°F. Place the split sub rolls on a baking sheet, cut-side up. Toast in the oven for 3 to 5 minutes, until golden and crisp on the edges. Add a slice of provolone cheese to the bottom half of each roll during the last minute if you like it melted.

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Prick sausages with a fork before browning to prevent bursting and ensure even cooking.
- 2Don't overcrowd the skillet when browning sausages—work in batches if needed for a deep crust.
- 3Let peppers and onions sit undisturbed for a couple of minutes to develop caramelized char marks.
- 4Deglaze the pan thoroughly with tomatoes to lift all the browned flavor bits into the sauce.
- 5Slice sausages into thick rounds before simmering so they stay juicy and soak up the sauce.
- 6Scoop out some soft bread from the roll's top to create a well that holds all the fillings.
- 7Toast rolls just until golden—over-toasting makes them too hard to bite through.
