Mix all of the ingredients for the chimichurri together, season well and set aside.
Preheat your BeefEater BBQ to a high heat. Drizzle the lamb with the oil and season well. Turn the heat down to medium-high and cook the lamb for 1 min on each side, then for another 2 mins each side until cooked through. Allow to rest on a board, loosely covered with foil for 3 minutes.
After the lamb has rested, slice on the diagonal and arrange on a serving board or plate and drizzle over the chimichurri. Scatter over the feta and pomegranate seeds to serve and enjoy!
