Preheat oven to 180°C.
Place a large flameproof casserole dish over a medium heat and add the oil. When hot add the chicken, onions and garlic. Cook for a few minutes, stirring constantly until the onions and chicken is lightly browned. Stir through the spices, chilli and herbs, cook for a few seconds.
Add the stock or water, peanut butter, tomato, kumara or pumpkin, salt and pepper. Bring to a gentle simmer and cook for 10 minutes. Cover the casserole dish with a tight-fitting lid and place in the oven to cook for 30 minutes. Remove from the oven and adjust seasoning to taste.
To serve: top with the fresh coriander and chopped peanuts. Serve with lime wedges on the side. This stew is great served with brown rice or warm chapattis.
