  • 1 lb sweet Italian pork sausages Any flavor of sausage will work
  • Fresh hoagie rolls
  • 1 green bell pepper, cut into bite-sized pieces
  • 1/2 red onion, cut into bite-sized pieces
  • 1 cup sliced baby bella mushrooms
  • 1 TBSP avocado oil
  • Sea salt and cracked black pepper
  • Provolone cheese slices; enough for each roll.

Sweet and Smoky Mustard Sauce.

  • 1/3 cup old style stone ground mustard
  • 2 tsp honey
  • 1 tsp liquid smoke You could also use 1 tsp smoked paprika if you don't have liquid smoke
  • 1 tsp Plain Greek yogurt


  • Preheat the oven to 400º F.
  • Transfer your chopped veggies to a mixing bowl. Drizzle the oil over them and season with salt and pepper; toss to coat.
  • Place the sausages onto a sheet pan and add the vegetables. Place the sheet pan in the oven for about 20-25 minutes, stirring the veggies halfway through. About 5 minutes before the sausages are ready, top them with a slice of provolone cheese. If you want to toast the buns, now is the time to do that as well. You can toast the buns on a separate sheet pan or make room on your current sheet pan by carefully moving the sausages and veggies aside with a spatula (this also depends on the size of your sheet pan).
  • When everything done and ready, remove the pan from the oven and scoop the cheesy sausages into a bun, and top with veggies and a few dollops of the mustard sauce.

Sweet and Smoky Mustard Sauce.

  • Put all of the ingredients into a small bowl and stir well with a fork or spoon until well combined.
