Flavorful sauteed bell peppers and onions with Italian sausages make these Italian sausage subs a star of the sandwich world. Plus, the recipe makes three subs, because you’ll want to split the third!

  • 3 soft Italian buns
  • 2 tbsp oil
  • 3 Italian sausage links
  • 1 onion
  • 2 bell peppers
  • salt and pepper to taste



  1. Before starting to cook, toast buns either in a toaster, under a broiler or a grill.


  1. Heat 1 tbsp. of oil in a sauté pan over medium-high heat. Add the sausage and cook until well browned on all sides and cooked through, about 10 minutes. Remove from heat and let rest.

Peppers & Onions:

  1. As the sausages are cooking, slice the peppers and onions.

  2. Using the same pan as the sausages, reduce heat to medium and add the remaining oil. Saute vegetables until softened, about 8-10 minutes

  3. Assemble sandwiches and enjoy!


Here I try and limit the number of pans being used, but you can cut the cooking time in half by sauteing the vegetable in one pan and cooking the sausages in another. Alternatively, you can grill the sausages!

Also, while I like these Italian sausage subs as is, some like to jazz them up with added mustard or horseradish. You can also add pickled banana peppers or poblanos in the pepper mix!
