Season the chicken breast pieces with 1 tbsp of cajun seasoning, salt and pepper to taste. Heat olive oil in a large skillet over medium-high heat and sear chicken and sausage until browned on all sides. Remove chicken and sausage from pan and set aside.
To the same pan, add in the celery, onion, bell pepper, jalapeno and garlic and cook until tender and fragrant, about 3 minutes. Stir in the rice, thyme, oregano and remaining 1 tbsp Cajun seasoning and toast for an additional 1 to 2 minutes, stirring occasionally.
Pour in the chicken broth, crushed tomatoes and hot sauce, stir to combine. Add in the okra and bring mixture to a simmer. Return the chicken and sausage to the skillet and stir to combine. Cover and cook for 18 to 20 minutes, stirring occasionally, until the rice is cooked through and tender.
Finally, add in the shrimp, stir into the hot rice mixture. Cover and cook an additional 5 minutes, until the shrimp is no longer opaque and cooked through. Garnish with chopped green onions and enjoy!
