In a large pot over medium heat, brown the sliced chicken andouille sausage until golden, then remove and set aside.
Add the avocado oil and cassava flour to the same pot, whisking constantly for 5-7 minutes until the roux turns a deep caramel color.
Stir in the diced onion, bell pepper, and celery, sautéing until the vegetables are soft and the aroma is fragrant.
Add the minced garlic, creole seasoning, thyme, sea salt, and black pepper, stirring for one minute to toast the spices.
Slowly pour in the chicken bone broth while whisking to incorporate the roux, then add the sliced okra and the browned sausage back to the pot.
Bring the mixture to a gentle boil, then reduce heat and simmer for 15 minutes until the gumbo has thickened.
Stir in the raw shrimp and cook for 3-4 minutes until they are pink and opaque.
Steam the cauliflower rice in a separate pan or microwave until tender.
Ladle the hot gumbo over the cauliflower rice and garnish with fresh chopped parsley.
