Heat the olive oil in a large heavy-bottomed pot over medium heat.
Add the sliced andouille sausage and sauté for 3-4 minutes until the edges are crispy and browned.
Add the cubed chicken breast to the pot and cook until browned on all sides, approximately 5 minutes.
Stir in the diced onion, green bell pepper, and celery, cooking until the vegetables are softened and translucent.
Incorporate the sliced okra, tomato puree, creole seasoning, sea salt, and black pepper, stirring to coat the meat and vegetables.
Pour in the chicken bone broth and bring the mixture to a gentle boil.
Reduce the heat to low, cover the pot, and simmer for 15-20 minutes until the gumbo has thickened naturally from the okra.
Ladle the gumbo into a bowl, place the cooked white rice in the center, and garnish with fresh parsley before serving.
