Instructions
Preheat the oven to 230C (450F). Put the oven rack on the lower half of the oven.
Rub the anchovy and garlic paste all over the lamb. Season with salt and pepper and sprinkle with a little rosemary and thyme.
Arrange all the sliced vegetables, slightly overlapping, over the bottom of the pan. Add the sliced garlic and sprinkle with the remaining rosemary, thyme and oregano. Squeeze half a lemon over the vegetables and drizzle with a little olive oil. Season with salt and pepper and add enough white wine to just cover the vegetables (you can also use stock instead of wine).
Set the rack over the vegetables and place the lamb, skin side up, on it. Drizzle with a little olive oil.
Roast for 15 minutes in the hot oven then lower the temperature to 180C (350F) and cover loosely with foil. Cook for another 15-20 minutes (depending on how rare you like it - it is best when a little rare) then take the meat out of the oven and rest it, covered loosely with foil, for 15 minutes.
The potatoes should be done by the time the meat has rested. Slice the lamb and serve with the vegetables and a nice Greek salad.
