Ingredients:

  • 1 tablespoon olive oil (15 ml)
  • 1 large onion, thinly sliced (about 1 cup)
  • 2 bell peppers (any color), seeded and sliced into strips (about 2 cups)
  • 1 pound hot Italian sausage (about 450g), casings removed or scored
  • 1 teaspoon dried oregano (5 ml)
  • ½ teaspoon red pepper flakes (2.5 ml), or more to taste (optional)
  • ½ cup chicken broth (120 ml)
  • Salt and freshly ground black pepper to taste
  • 4 hero rolls (hoagie rolls, submarine rolls), about 6-8 inches long
  • Optional toppings: provolone cheese, grated Parmesan cheese, marinara sauce, mustard

Instructions:

  1. Heat the olive oil in a large skillet over medium heat. Add the sliced onions and bell peppers and cook, stirring occasionally, until softened and slightly caramelized, about 8-10 minutes. Season with salt and pepper. Remove from the skillet and set aside.
  2. Add the sausage to the same skillet. Cook, breaking it up with a spoon, until browned and cooked through. Drain off any excess grease.
  3. Return the sautéed vegetables to the skillet with the sausage. Stir in the dried oregano and red pepper flakes (if using). Pour in the chicken broth and bring to a simmer. Cook for about 5 minutes, allowing the flavors to meld.
  4. Slice the hero rolls lengthwise. Spoon the sausage and pepper mixture evenly into each roll.
  5. If desired, top with provolone cheese and broil briefly until the cheese is melted and bubbly. Or, sprinkle with Parmesan cheese or drizzle with marinara sauce or mustard.
  6. Serve immediately.
