Cut the lamb into 2.5cm chunks.
Combine the ingredients and pour over the meat cubes. Mix thoroughly, chill and marinate for 3-6 hours (or overnight).
If you're using wooden skewers, soak them 30 minutes before cooking to stop them burning.
Heat a grill, barbecue or griddle pan. Thread the chunks of lamb onto 4-6 skewers. Season, then grill for about 5-10 minutes, turning regularly, until they're cooked to your liking.
Rest for a couple of minutes before serving.
Serve with salad and/or grilled veggies or tucked into grilled pita or flatbread with salad. Drizzle with a yoghurt dressing.
