Cut bell peppers in half from top to bottom, remove seeds and gently scoop out the white ribs.
Drizzle 1/4 teaspoon of olive oil over each pepper half and use your fingers to rub the oil over the inside and outside. Combine 1/2 teaspoon of salt and 1 teaspoon of Creole seasoning and sprinkle over the inside of the pepper halves.
Place the peppers in a 9x13 inch baking dish and put them into the oven to cook for 15 minutes.
In a small bowl combine the dried thyme, Creole seasoning, and the remaining ½ teaspoon of salt.
Heat a large skillet over medium high heat and add 1 tablespoon of olive oil to it.
Place the cubed chicken breast into the pan and sprinkle with half of the Creole spice mix. Let the chicken brown for 2-3 minutes then add the diced sausage to the skillet and cook until slightly browned. Remove sausage and chicken and set aside in a bowl.
Pour in the remaining 2 teaspoons of olive oil and add the onion and celery to the pan, cook until softened, approximately 5 minutes. Add the garlic and cook for 2 minutes more.
Return the chicken and sausage to the skillet with the onion mixture and add the remaining Creaole spice mix, diced tomatoes and green chiles, and cauliflower rice. Cook until the cauliflower rice is tender, approximately 5 minutes, stirring to toss everything together.
Remove the cooked peppers from the oven and use a slotted spoon to stuff each one with equal amounts of the chicken and sausage mixture (approximately 4 ounces per pepper half).
Place the stuffed peppers back in the oven to bake for 15 minutes more.
