Heat a large pan or dutch oven over medium-high heat. Once warm, add the beef and chicken liver to the pan, breaking it up with a wooden spoon as it cooks. Once it is cooked through and no longer pink, drain any excess drippings from the pan.
Add the onion, celery, garlic, cajun seasoning and salt. Stir occasionally and cook for 5 to 7 minutes until the onions and celery are soft.
Add the cauliflower rice and stir to combine everything. Cook until the cauliflower meets your desired texture. Divide between bowls and enjoy!
