Konjac noodles are basically a free food: They contain only seven calories a cup, because you can't digest them, but the good bacteria in your gut sure can. And that's good news for you, because it acts as a prebiotic. Better yet, they come precooked, so all you need to do is warm them up and toss with your favourite fresh ingredients. Add some of Julie's light Asian dressing to the mix and you've got yourself a lovely, healthy lunch.
