Be sure to check labels though as carb counts will vary based on brand, and some may not be good choices. Cabbage is a great vegetable choice for anyone watching their carbs and eating keto due to it's low net carb content. Cruciferous veggies have a good deal of health benefits and cabbage when lightly sauteed, as in this recipe maintains a nice crunchy texture.
