Trim any excess fat off the chicken thighs. Season the meat. Heat the oil in a large frying pan, pack in the thighs, skin-side down, and cook for 8-10 mins until the skin is a good golden colour. Turn them over and cook for another 5 mins. Take out with tongs and set aside on a plate. Drain off all but about 1 tbsp fat from the pan.
Add the onion wedges and garlic to the pan and cook for 5 mins. Meanwhile, roughly grind the spices in a pestle and mortar. Stir them into the pan and cook for 5 mins.
Add the chickpeas and stock. Bring to the boil, put the chicken thighs back in, skin-side up, and simmer, uncovered, for about 15-20 mins until the chicken is tender.
Stir in spoonfuls of Greek yogurt and let it warm through, but don’t allow it to boil. Sprinkle with coriander leaves and serve hot with bread.
