Preheat your oven to 180°C (356°F).
Slice the bell peppers in half lengthwise and remove seeds and membranes. Place them in a baking dish, cut side up.
In a pan, heat olive oil and sauté onions until soft. Add garlic and cook for another minute.
Add the ground beef and cook until browned. Season with smoked paprika, salt, and pepper.
Stir in the tomato passata and let it simmer for 5–7 minutes. Then, stir in the cream cheese until melted and creamy.
Spoon the beef mixture into each pepper half. Sprinkle shredded cheese generously over the top.
Bake for 25–30 minutes or until the cheese is golden and bubbly.
Sprinkle with fresh parsley before serving, if you're feeling fancy.
