In case you needed another reason to try the above basil pesto (other than it sounding amazing and the multitude of uses), herbs are nutritional powerhouses. Herbs (and spices) not only contain virtually no calories, but they are packed with antioxidants, vitamins and minerals. For example, the 1 cup of basil in the recipe only contains 6 calories, while at the same time packing in tons of Vitamin K as well as calcium, iron, Vitamin C, magnesium and more. Herbs and spices are one of the healthiest ways to add flavor to your food without adding calories and fat. So, what are you waiting for? Go mix up some pesto for dinner tonight.
