Boil the brown rice according to the directions on the packet - say around 40 minutes ( I use the absorbtion method on the stove). Cook the egg in a large frying pan coated with oil, omlette style. Remove and slice. Then cook prawns until firm and pink. Add vegetables and stir fry. Return the egg to the pan. Then add all the rice and add the soy sauce until the taste is to your liking. Serve hot as a complete and delicious meal.
