Most people don't think much about radishes outside of perhaps a few slices in a salad. But radishes have a lot of great potential in a low-carb diet. Did you know that it takes 10 medium radishes to get a gram of carbohydrate? And that they are great steamed, or roasted in the oven? When cooked, they lose some of their "bite", and take to a variety of herbs or spices.
