Begin by preparing all of your ingredients and having them ready to add to the pan.
Heat a splash of oil in a large, heavy based saucepan or Dutch oven and add the smoked sausage. Cook for a few minutes on medium-high heat, stirring occasionally.
When the sausage begins to colour, add the chicken pieces and continue to cook until the sausage and chicken pieces begin to brown. Don’t worry if they’re not entirely cooked. Remove from the pan and set aside.
In the same pan, add another generous splash of oil and increase the heat to high. Heat the oil for a minute or two, then add the diced onion, celery and peppers. Cook over high heat, stirring often, until the vegetables begin to soften. Once soft and lightly caramelised, add the garlic, Cajun seasoning, thyme, oregano, bay leaves, black pepper and a generous pinch of salt to the pan. Cook for another minute or so, stirring often.
Stir in the tomatoes, hot sauce and Worcestershire sauce, followed by the rice. Stir to combine, then slowly pour in the chicken stock and bring to the boil. Reduce the heat to low, cover and simmer for around 20-25 minutes, stirring occasionally, until the rice has almost cooked and the liquid has evaporated.
Add the prawns to the pan and stir. Recover the pan and continue to cook over low heat until the prawns are cooked, stirring occasionally.
Taste for seasoning, add more salt and pepper if necessary, then serve in bowls topped with chopped spring onions.
