Ingredient Notes and Substitutions

See the complete list of ingredients on the recipe card below.

Italian sausages: We love Johnsonville Italian sausage. They are available in sweet, mild, and hot.
Bell pepper: You can use any color bell pepper. I love the flavor and color contrast between red and green bell peppers.
Dried Italian seasoning: Dried or fresh herbs like thyme, rosemary, basil, and parsley
Marinara sauce: I like Rao’s and Kirkland Organic Marinara, but you can use your favorite brand. If you have time, make homemade marinara sauce.
Cheese: You can use any Italian cheeses that melt well, such as Mozzarella, Provolone, Provel, or Fontina.
Hoagie rolls: Also known as sub rolls. You can substitute French baguettes.

Preparation Tips

Don’t overcook the bell peppers and onions. They are better when they are not too soft.
Butter the buns before you toast them! You can use unsalted or salted butter. It adds a lot of flavor, and if you have time, rub them with a garlic clove.
These are best eaten after preparation, but you can gently reheat them in the microwave at reduced power.
