After the meat is browned, reduce the heat to medium and add the onion, celery and bell pepper. Continue to cook for about 5 minutes until the veggies are tender and the onions are translucent. Add the minced garlic and the next four ingredients and cook for about another minute.
Add the frozen cauliflower rice, chicken stock or water and season with the remaining ½ tsp. salt and ½ tsp. garlic powder. Combine thoroughly and use the liquid to loosen and deglaze the bottom of the pan. Continue to cook, stirring often, until the cauliflower rice is soft and there is no extra liquid left in the pan.
