1 Heat the oil in a large pan, then fry the onions for 6 mins until starting to turn golden. Add the garlic, carrots and thyme, and cook for 4 mins more. Stir in the mince, breaking it up with the spoon. When it has turned brown, add the lentils and swede with the flour. Cook for 1-2 mins, then gradually add the stock and red wine. Cover and simmer for 35-40 mins.

2 Meanwhile, boil all the potatoes for 15-20 mins until tender, then drain and mash with the yogurt, nutmeg and black pepper. Spoon the meat mixture into a 2-litre ovenproof dish and spread or pipe the potato mixture on top. Grill until the topping starts to brown. (If making ahead, reheat in the oven at 180C/160C fan/gas 4 for 45 mins.) Serve with green vegetables, such as peas and broccoli, if you like.
