Dice the chicken breast into bite-sized pieces and thinly slice the andouille sausage.
Heat the olive oil in a large skillet or pot over medium-high heat.
Add the chicken and sausage to the pan, browning for 5-6 minutes until the chicken is cooked through.
Stir in the diced onion, celery, and green bell pepper, sautéing until the vegetables are softened and fragrant.
Add the minced garlic, smoked paprika, thyme, garlic powder, onion powder, cayenne, salt, and pepper, stirring for 1 minute to toast the spices.
Pour in the crushed tomatoes, chicken bone broth, and pre-cooked brown rice.
Reduce the heat to low and simmer for 10 minutes, allowing the flavors to meld and the liquid to thicken into a rich sauce.
Garnish with fresh parsley or green onions if desired and serve warm.
