While the chicken is cooking, make the rice & peas. Rinse the rice in a sieve until the water runs clear. Bring a pan of water to the boil with the liquid only from the kidney beans, the coconut milk, spring onions, thyme, garlic, allspice and some salt, then simmer for 10 mins. Add the beans, then simmer for 5 mins more until the rice is tender. Drain and serve straight away with the chicken.
