Dice the chicken breast into bite-sized pieces and slice the andouille sausage into thin rounds.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken and sausage to the pan, browning for 5-6 minutes until the chicken is cooked through and the sausage is fragrant.
Stir in the diced onion, bell pepper, and celery, sautéing for 4 minutes until the vegetables begin to soften.
Add the minced garlic, smoked paprika, oregano, thyme, cayenne, salt, and pepper, stirring for 1 minute to toast the spices.
Pour in the tomato puree, chicken bone broth, and cauliflower rice, stirring well to combine all ingredients.
Reduce heat to medium, cover, and simmer for 5-7 minutes until the cauliflower rice is tender and most of the liquid has been absorbed.
Garnish with freshly chopped parsley and serve immediately.
