Chef Rocco DiSpirito's negative calorie salad recipe is a healthy alternative to the additive and sugar heavy salad dressings we are used to consuming. It's a big, green, leafy salad that will leave you feeling refreshed and energized. All the negative calorie vegetables in this salad actually have less calories than your body burns metabolizing them, so you're going to be ahead of the game! It's simple and takes only a few minutes to prepare. Give it a try if you are craving something light for either lunch or dinner.
