Wash and clean the chicken pieces. Keep this aside.
In a bowl, mix curd, red chilli powder, coriander powder, turmeric powder, garam masala powder, cumin powder, lemon juice, coriander leaves, salt, ginger and garlic paste finely.
Add this mixture over the chicken, tomatoes, capsicum and onion pieces and mix well with hand, so that everything will be well incorporated.
Meanwhile soak the bamboo skewers in water for about 30 minutes. Thread the marinated chicken, capsicum, tomato and onions one after the other on the skewers.
Repeat the process till all the pieces are threaded in the skewer.
Preheat the oven to 200 degrees Celsius and grill the chicken skewers for about 30- 40 minutes.(Place these skewers on the top most rack that is near to the coil).
Smear oil and turn the skewers in between so that they get cooked evenly.
When it is done, remove them on a plate and enjoy this along with mint chutney.
