Combine all of the seasonings into a small bowl, set aside.
Heat a large skillet over medium heat with the ghee. Add the onion, garlic, bell pepper, and andouille sausage. Cook, stirring often, until the veggies are tender, about 5 minutes.
Add in the seasoning mixture and toss until well combined and continue to cook, stirring, toasting the spices to bring out more flavor, about 2 more minutes.
Pour in the cauliflower rice and green onions and toss until well combined. Cook, stirring, until the cauliflower rice is just tender but not soggy, 4 to 5 more minutes.
