Heat the oil in a large frying pan with a lid.
Add the chicken and chorizo and cook until the chicken is cooked and the chorizo has browned slightly.
Add in the onion and cook for a few minutes until soft.
Add the capsicum, mushrooms, and Creole Seasoning. Cook for 5 mins more.
Add the uncooked rice, tomatoes and stock
Cover and simmer for 20-25 mins until the rice is tender stirring every so often so it doesn't stick to the bottom of the pan.
Add more chicken stock if it gets a bit too dry.
Once the rice is cooked, add the prawns and cook for a couple of minutes until the prawns turn a pick colour. Then turn off the fry-pan and let it sit for a few minutes.
