Preheat the oven to 200 C / Gas 6. Rub the lamb with the spices.
Heat 1 tablespoon oil in a large non stick frying pan over a high heat, sear the lamb all over for 6 minutes, until you have a nice golden crust. Transfer to a baking tray and cook in the oven or 10 minutes for a pink centre, longer for well done. Remove and allow to rest for at least 15 minutes.
Meanwhile lay the pitta bread on a baking tray, drizzle with a little extra oil and cook for 10 minutes or until golden and crisp.
Scatter the herbs over the base of a large platter, sprinkle over the feta cheese and pomegranate seeds, scatter with the pitta croutons then top with thinly sliced pieces of lamb and a squeeze of lemon juice and the remaining tablespoon of olive oil.
