Slice the chicken breast and andouille sausage into bite-sized pieces.
In a large heavy-bottomed pot over medium heat, brown the sausage for 3-4 minutes until crisp, then remove and set aside.
Add the avocado oil and whole wheat flour to the same pot, whisking constantly for 8-10 minutes until the roux reaches a deep chocolate brown color.
Stir in the diced onion, celery, and green bell pepper, sautéing for 5 minutes until the vegetables are softened and aromatic.
Add the minced garlic, smoked paprika, cayenne, thyme, sea salt, and black pepper, stirring for 1 minute to toast the spices.
Slowly pour in the chicken bone broth while whisking vigorously to incorporate the roux and prevent lumps.
Return the sausage to the pot along with the raw chicken pieces, sliced okra, and the bay leaf.
Reduce heat to low and simmer for 20-25 minutes until the chicken is tender and the gumbo has thickened naturally.
While the gumbo simmers, steam the cauliflower rice in a separate pan or microwave until just tender.
Remove the bay leaf and serve the hot gumbo over the cauliflower rice, garnished with freshly chopped parsley.
