Heat a large Dutch oven or heavy-bottomed pot over medium heat.

Add the sliced sausage and cook until browned, then remove from pot and set aside.

Add the diced chicken breast and cook until browned and cooked through, then remove from pot and set aside.

Add the diced onions, bell pepper, celery, and minced garlic to the pot, cooking until the vegetables are slightly softened.

Add the rice to the pot, stirring until it is coated with the oil and vegetables.

Pour in chicken broth, then add in Cajun seasoning and salt and pepper to taste.

Bring the mixture to a boil and cover with a lid, cooking over low heat for 18-20 minutes.

When the rice is almost tender, add the cooked sausage and chicken back into the pot and stir all the ingredients together.

Cover the pot again and cook for another 5-7 minutes until the rice is fully cooked and the flavors have melded together.

Garnish with chopped green onions and serve.
