2) Combine the yoghurt with the spices and zest of lime in a large bowl.
3) Cut the chicken into large chunks and season liberally with salt and pepper. Add to the yoghurt mixture and toss to coat evenly. Put a small wire rack on a baking sheet or a slotted broiler pan. Arrange the chicken on the rack or slotted pan and roast until charred at the edges and juices run clear, about 15 mins.
4) Combine the apple, tomatoes and spring onions in a serving bowl. Add the lime juice, oil, and salt and pepper, to taste, and toss to combine.
5) Transfer the chicken to a serving platter and serve with apple-tomato topping and warm bread.
