Add the chicken and sausage to the pot, and sprinkle about 1 tbsp of the cajun seasoning over the chicken. Stir everything together and cook until the chicken is no longer pink and is cooked through, about 5 minutes.
In a large skillet or Dutch oven heat the olive oil. Add the shrimp and cook on both sides until it turns pink, about 2 min per side, could be less depending on the size of your shrimp. Remove the shrimp from the pot and set aside.
Season the shrimp with about ½ tbsp of the cajun seasoning and set aside.
