Ingredients
Scale
For the Sausage and Peppers
- 4 Italian sausages (in their casings)
- 3 tablespoons extra-virgin olive oil, divided
- 1 large onion, cut in half vertically, then into 1/4-inch slices
- 1 1/2 teaspoons kosher salt, divided
- 3 bell peppers (green, red, yellow), seeded and cut into 1/4-inch slices
- 2 cloves garlic, pressed or minced
- 1/4 teaspoon red pepper flakes
- 1 tablespoon balsamic vinegar
For the Sandwich
- 4 hoagie rolls
- Grainy mustard, mayo, or pesto mayo (optional), for serving
- Slices of white cheese (such as provolone, havarti, or Swiss)
Instructions
- Brown the Sausages: Add the sausages to a large skillet with 1 tablespoon of olive oil. Set over medium heat and cook for 5-7 minutes, turning frequently until each side is evenly browned. Remove from the heat, cover, and let them rest.
- Sauté Onions: In the same skillet, add the remaining 2 tablespoons of olive oil over medium heat. Add the onion and season with 1 teaspoon of salt. Sauté for 10 minutes, stirring occasionally. If onions brown too quickly, lower the heat to medium-low.
- Add Peppers and Garlic: Add the sliced bell peppers, minced garlic, remaining ½ teaspoon salt, and red pepper flakes. Stir to combine, then cook for 10-15 minutes, until the peppers are softened but still have a slight crunch.
- Deglaze and Reheat Sausages: Add the balsamic vinegar and stir, scraping any browned bits from the skillet. Return the sausages to the pan. Reduce heat to low, cover, and let everything warm together for a few minutes before assembling.
- Toast Rolls and Assemble Subs: Lightly toast the hoagie rolls in a toaster oven or under a broiler. Spread with mustard, mayo, or pesto mayo if desired. Load with sausage, peppers, and onions, then top with cheese slices.
- Melt Cheese and Serve: Place assembled subs back under the broiler or in the toaster oven to melt the cheese. Serve hot and enjoy!
Notes
- Use sweet or spicy Italian sausages according to your preference.
- Hoagie rolls can be swapped for baguettes or ciabatta.
- If you like more heat, increase the red pepper flakes or use hot Italian sausage.
- Mayo or pesto mayo adds extra flavor, but the sub is delicious without condiments, too.
