Cut the chicken into bite-sized cubes and put them in a deep bowl. Put the yoghurt in a food processor and add the garam masala, ground coriander, ginger, mint sauce, garlic, chilli powder, salt, fresh coriander and red chilli. Whisk everything together for about 30 seconds. Pour this over the chicken, mix well and leave to marinate for about half an hour. Prepare the vegetables and stir them into the marinade as they are ready. Preheat a moderate grill, add the oil to the marinade mixture and mix everything together well. Arrange the chicken cubes alternating with pieces of vegetables on skewers and grill for 7-10 minutes, turning the skewers from time to time and brushing with the marinade, until the chicken is cooked through and scorch marks begin to appear on top of the chicken and vegetables. Serve sprinkled with the lemon juice and garnished with lime slices. DISCLAIMER? Copyright 1996 - SelecTV Cable Limited. All rights reserved. Carlton Food Network http://www.cfn.co.uk/
