You can make a smaller version of this by using an 8-inch cast iron. Use 1lb ground beef, 2 cups riced cauliflower (about ½ head), 1 ½ cup shredded cheese, 4 oz sour cream, ½ cup shredded carrot, ½ red bell pepper, and 1/3 cup green onion. Taste and season with approximately 1 ½ - 2 tbsp of taco seasoning. Salt to taste. Follow same preparations and cooking directions.
