Prepare the pasta in boiling salted water according to the instructions on the packet. Heat the oil in a frying pan. Fry the minced meat for 3-4 minutes while turning. Peel onion and garlic, dice finely, add to mince and fry for 1-2 minutes, season with salt and pepper.
Put the bell peppers with the juice in a high container and puree finely. Add the harissa, stock and pureed paprika to the mince and bring to the boil. Wash the parsley, dab dry, pluck the leaves from the stalks and chop, except for something to garnish.
Stir the parsley into the sauce. Drain the pasta and rinse briefly with cold water. Layer together with the minced sauce in a tart dish (without lift-off base) or an oven dish. Crumble the cheese and sprinkle over the noodles.
Bake in a preheated oven (electric range: 225 °C/ convection oven: 200 °C/ gas: level 4) for 7-10 minutes until brown. Remove, let cool slightly and garnish with parsley leaves.
