Add shrimp and sausage to a medium-sized bowl and season with cajun seasoning to taste. Heat a large skillet over medium heat and add 1 tbsp of avocado oil. Once oil is hot, add shrimp and sausage to skillet and cook until shrimp is opaque. Remove shrimp and sausage from skillet, add to a plate and set aside.
Add the remaining 1 tbsp of avocado oil to skillet and add onion, bell pepper and celery. Cook until vegetables have softened, about 5 minutes. Add garlic and cook for an additional 1 minute.
Next, add the tomato sauce and 1 tbsp of cajun seasoning to the vegetables and stir to combine. Cook until the sauce is warm, about 3 to 5 minutes.
Add frozen cauliflower rice to sauce and stir to combine. Cook until the sauce has reheated.
Once sauce has reheated, add the shrimp and sausage back into the skillet and stir to combine. At this point, I recommend tasting your jambalaya to see if you need to add any additional cajun seasoning.
Garnish Jambalaya with green onions and serve.
