Ingredients
  

  • 4 large bell peppers (any color; red or yellow are sweetest)
  • 1 pound lean sirloin or flank steak, very thinly sliced (or shaved steak)
  • 1 tablespoon olive oil
  • 1 large yellow onion, thinly sliced
  • 8 ounces cremini or button mushrooms, sliced
  • 1 small green bell pepper, thinly sliced (for the filling; optional but classic)
  • 2 cloves garlic, minced
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon low-sodium soy sauce or coconut aminos
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • Salt and black pepper, to taste
  • 6–8 slices provolone or 1 cup shredded provolone (reduced-fat if you prefer)
  • Optional: 1/4 cup light cream cheese or Greek yogurt for creaminess
  • Optional garnish: chopped parsley or chives
  • Cooking spray

Method
 

  1. Prep the peppers: Preheat the oven to 400°F (200°C). Halve the bell peppers lengthwise and remove seeds and membranes. Lightly coat a baking dish with cooking spray and place the pepper halves cut-side up. Sprinkle with a pinch of salt and pepper.
  2. Par-roast for tenderness: Roast the pepper halves for 12–15 minutes until slightly softened but still holding their shape. This helps them cook evenly once stuffed.
  3. Slice the steak thin: For best results, place the steak in the freezer for 15–20 minutes before slicing. Slice against the grain into very thin strips. Pat dry and season with salt, pepper, and the smoked paprika.
  4. Sauté the veggies: Heat olive oil in a large skillet over medium-high heat. Add onions, mushrooms, and the thinly sliced green pepper (if using). Cook 6–8 minutes, stirring occasionally, until tender and browned. Stir in garlic and cook 30 seconds.
  5. Season and splash: Add Worcestershire and soy sauce to the veggies. Stir to coat and let the liquid reduce slightly for concentrated flavor. Transfer the mixture to a bowl.
  6. Quick-sear the steak: In the same hot skillet, add the sliced steak in a single layer. Sear 1–2 minutes per side until just cooked through. Avoid overcooking—thin beef dries out fast. Return the veggie mix to the pan and toss to combine. Adjust salt and pepper.
  7. Add creaminess (optional): For a richer texture, stir in light cream cheese or a spoonful of Greek yogurt off the heat until just melted and silky.
  8. Stuff the peppers: Remove the par-roasted peppers from the oven. Divide the steak and veggie mixture evenly among the halves. Top each with a slice of provolone or a generous sprinkle of shredded cheese.
  9. Bake to melt: Return to the oven for 8–10 minutes, until the cheese is melted and bubbly and the peppers are tender.
  10. Finish and serve: Rest for 3–5 minutes. Garnish with chopped parsley or chives. Serve hot with a simple side salad or roasted potatoes if you want extra carbs.
