In a bowl, combine the Yoghurt and spices, then stir in the diced lamb. Set aside for at least 30 minutes.
Meanwhile make the kachumber salad, by combing all the ingredients. Set aside.
To make the Mint Yoghurt, combine the yoghurt and mint sauce. Whisk until combined.
Preheat an overhead grill or broiler.
Remove the lamb from the fridge and thread it onto four metal skewers. Once skewered, place under the grill. Grill for 12-16 minutes until golden brown. Turn at least once while cooking.
Allow the skewers to rest for 5 minutes.
While the skewers rest, wrap the naan bread in kitchen foil and warm them under the hot grill for two minutes. Be careful as the foil will be hot.
When ready, spread a tablespoon of mango chutney across each naan bread. Add a liberal sprinkling of Iceberg lettuce and a large spoonful of kachumber salad then lay the skewers across each naan bread.
Garnish with more kachumber and a heavy dose of raita. Finish with chopped coriander and mint.
