Prepare the Filling: Heat a pan over medium heat and add oil. Add the diced red onion and fry until fragrant. Add the ground cumin, dried oregano, and crushed garlic, and fry for an additional minute. Add the ground pork mince and cook until browned. Stir in the tomato paste or tomato sauce and the soy sauce or Worcestershire sauce—season with salt and black pepper to taste.
Prepare the Peppers: Preheat the oven to 180 degrees Celsius. Place the de-seeded and sliced red bell peppers on a baking tray. Drizzle with oil and season with salt and black pepper. Roast for 10 minutes.
Stuff the Peppers: Remove the peppers from the oven. Scoop the cooked pork mixture into each pepper half. Top with creamed cheese, grated cheese, salami rounds, and soft feta cheese.
Bake the Stuffed Peppers: Return the stuffed peppers to the oven and bake for 10 minutes or until the cheese is melted and bubbly.
Serve: Remove from the oven and garnish with fresh basil or oregano. Serve immediately and enjoy!
