How to Make It
Heat oil in a Dutch oven over medium-high. Add chicken and sausage, and cook, stirring constantly, until browned on all sides, 8 to 10 minutes. Remove with a slotted spoon to paper towels; blot with paper towels.
Add onion, bell pepper, celery, garlic, bay leaves, Creole seasoning, thyme, and oregano to hot drippings; cook over medium-high until vegetables are tender, 5 to 7 minutes. Stir in rice, and cook until fragrant, about 3 minutes. Stir in chicken broth, tomatoes, chicken, and sausage. Bring to a boil over high. Cover, reduce heat to medium, and simmer, stirring occasionally, until rice is tender, about 20 minutes. Garnish with sliced scallions, if desired.
