Heat the oil in a large cast iron skillet over medium heat. When the oil is hot, add the sausage links and brown them slowly. Cover the pan loosely with a piece of aluminum foil to help keep heat in and keep the splatter down.
Brown the sausage links slowly. Should they start to brown too quickly and crack, turn your heat down. Keep turning the sausage with tongs to brown all sides.
When the sausage is browned remove from the pan and set aside.
Sauté onions and peppers
Melt the butter in the skillet. Add the sliced peppers and onions. Season them with salt and pepper to taste.
Use a wooden spoon to toss them in the pan to coat with evenly with fat. Cook over medium to low heat until they are slightly softened. Add the honey and minced garlic and stir.
Stir onions and peppers occasionally with a wooden spoon as they cook.
Deglaze the pan (optional)
Add Marsala or dry red wine to deglaze the pan. Use a wooden spoon to scrape the brown bits on the bottom of the skillet. Season again with salt and pepper, if needed.
Simmer all ingredients
Add back the sausage links, add the marinara sauce and simmer ingredients over low heat. Simmer until the peppers are soft and sausage links are cooked all the way through.
Keep the sausage links whole or slice into pieces.
Sausage and peppers sandwich
Slice Hoagie rolls ⅔ way through. Place on half sheet pan lined with parchment paper.
Spoon sausage, peppers and onions into each roll. Spoon additional marinara sauce over top if desired.
Add two slices of Provolone or Mozzarella cheese, if desired.
Cook in a preheated 400 degree F oven for about 6-8 minutes, or until the cheese is melted. Garnish with freshly grated Parmesan cheese. Enjoy immediately.
If you want the cheese to be browned more, place on broil for a few minutes. Monitor carefully so you don't burn them.
Notes
Feel free to use different colored bell peppers, or just stick with one color. This recipe uses sweet sausages, but you can also use hot sausage or a combination of both if you prefer.Serving a crowd? Make a larger recipe and keep it warm in a slow cooker to serve to guests.
