Dice the chicken breast into bite-sized pieces and slice the chicken andouille sausage into rounds.
Heat the ghee in a heavy-bottomed pot or Dutch oven over medium heat.
Add the chicken and sausage, browning them for 5-6 minutes until golden, then remove from the pot and set aside.
Whisk the cassava flour into the remaining fat in the pot, stirring constantly for 3-4 minutes until the roux turns a light nutty brown.
Add the diced onion, bell pepper, and celery (the holy trinity) to the roux and sauté until softened, about 5 minutes.
Stir in the minced garlic, smoked paprika, thyme, cayenne, salt, and black pepper, cooking for 1 minute until fragrant.
Slowly pour in the chicken bone broth while whisking to prevent lumps, then add the okra and the browned meat back into the pot.
Bring to a gentle simmer, cover, and cook for 15-20 minutes until the gumbo has thickened slightly.
While the gumbo simmers, steam the cauliflower rice in a separate pan with a splash of water until tender.
Serve the hot gumbo over the cauliflower rice and garnish with freshly chopped parsley.
