Heat the olive oil in a large heavy-bottomed pot over medium heat.
Add the diced chicken breast and sliced turkey sausage, searing until golden brown on all sides, then remove and set aside.
Whisk the cassava flour into the remaining oil in the pot, stirring constantly for 3-5 minutes until it turns a deep golden brown roux.
Stir in the diced onion, bell pepper, and celery, sautéing until the vegetables are softened and translucent.
Add the minced garlic, smoked paprika, thyme, sea salt, black pepper, and cayenne, stirring for one minute until fragrant.
Slowly pour in the chicken broth while whisking continuously to prevent lumps from forming in the roux.
Return the chicken and sausage to the pot and add the sliced okra.
Reduce the heat to low and simmer for 20 minutes until the gumbo has thickened and the flavors are deeply melded.
