1. Mix the yoghurt with the garlic, paprika, cumin and lemon juice. Place the diced turkey into a shallow dish and pour over the yoghurt mixture. Cover lightly and leave to marinate in the fridge for as long as possible, (overnight is ideal). Stir occasionally during marinating.
2. When ready to cook, preheat grill to high and line the grill rack with tin foil. Thread the diced turkey onto the skewers and place under the grill. Cook on both sides for 2 minutes then reduce the heat and continue to grill for 10-12 minutes or until thoroughly cooked. Garnish with lemon wedges, parsley sprigs and serve with crusty bread and salad.
