Simple Spinach Parmesan Pesto

With a spinach pesto you can pack all of the antioxidants of 1/2 cup of raw spinach into one 2-tablespoon serving of sauce! The antioxidants have not been removed from the other phytonutrients in the spinach, therefore their absorption is uninterrupted!The only tool you need for this lovely sauce is a food processor or blender! The pesto keeps for about a week in the fridge.
