Crush 2 garlic cloves, chop 1 onion and 2 carrots, and slice 200g of mushrooms. Heat a non-stick frying pan and dry fry 450g of lean minced beef until brown. Add the garlic and onion and cook for 1-2 minutes. Next add the carrots and mushrooms and cook for 5 minutes, adding a splash of water to stop the mince drying out. Add 1 large can of chopped tomatoes, 2 tbsp of tomato purée, 100ml of red wine, 150ml of beef stock, mixed herbs and black pepper. Bring to the boil then simmer for around 30 minutes, adding extra stock if needed. While the Bolognese is simmering, cook 350g of wholewheat spaghetti according to the pack instructions. Drain and divide amongst 4 plates. Top with the Bolognese and serve with 1 tbsp of grated Parmesan cheese for each plate.
