Method

Preheat the oven to gas 3, 170°C, fan 150°C. Put the lamb in a large roasting tin and rub all over with the olive oil.
In a small bowl, combine the garlic, anchovy and lemon zest. Make slits all over the lamb and stuff with the garlic mixture. Drizzle or squeeze over the lemon juice, then scatter with the oregano and cinnamon; season well. Cover with foil and roast for 4 hours.
Remove the foil and increase the heat to gas 7, 220°C, fan 200°C. Cook the lamb for a further 25 mins, or until browned. Remove from the oven, cover with foil and leave to rest for 20-35 mins (while you cook the veg sides).
Meanwhile, combine the tzatziki ingredients in a small bowl; season well. Set aside until needed.
Transfer the lamb to a serving platter and carve into thick slices. Serve with the tzatziki and veg sides.
