Jamaican Rice and Peas

Rinse the rice in water and drain.
Put the rice and cooked beans in a heavy pot.
Measure the coconut milk and add enough water to make 2 cups.
Pour the coconut milk over the rice and beans and add two cups of water.
Break the onion in half and lay it on top of the coconut milk along with the thyme and pepper. Do not stir.
Bring the mixture to a boil and turn it down to low and cover the pot.
Cook for 30-40 minutes, or until all of the liquid is absorbed.
Let stand for a few minutes before removing the thyme, pepper and onion.
Season with salt to taste and serve.
