Cook the kippers as the packet instructions. Once cooked, cut into chunks and place aside. Meanwhile, heat the oil in a large pan and fry the onion over a low-medium heat for 10 minutes, until soft.
Add the spices and cook for 2 minutes making sure the spices are well mixed. Add the rice and peas to the pan, along with 2 tsp water.
Cook for 3-5 minutes, stirring, until the peas are cooked and the rice is piping hot; season.
