Stuffed Bell Peppers with Minced Meat and Mozzarella

Preheat the oven to 160 °C top/bottom heat and line a baking sheet with baking paper.

Wash the bell peppers, halve them, and remove the core.

For the filling, in a large bowl, mix the minced beef with the diced onion, crushed garlic cloves, egg, tomato paste, and dried rosemary. Season with salt and pepper.
