1. Preheat the oven to 180C/350F/gas mark 4. Cook the pasta according to the instructions on the pack. Drain and reserve.
2. Place the washed spinach in a large saucepan with 1 tablespoon of water. Cover and cook over a high heat for 2-3 minutes, shaking the pan occasionally. Drain and squeeze the spinach so all the water is removed. Reserve to one side.
3. Meanwhile, in a large non-stick saucepan, heat the oil over a medium heat. Fry the onion and garlic until they start to soften but do not colour. Add the mushrooms to the saucepan and continue to fry for a further 3-4 minutes. Remove from the pan and reserve.
4. Fry the pork mince in the same saucepan for 6-7 minutes or until brown. Remove from the heat and add the onions, garlic and mushrooms. Stir in the cooked pasta, spinach and crème fraîche and season well with salt and pepper.
5. Transfer the mixture to an ovenproof dish. Combine the breadcrumbs, cheese and parsley and sprinkle on top.
6. Cook in the centre of the oven, uncovered, for 40 minutes or until the top is golden. Serve immediately with a crisp green salad and focaccia, such as cheese and onion.
