Pesto arugula is a quick and easy recipe, very versatile. Thanks to my friend Erik and his beautiful garden, I can prepare this recipe with fresh organic arugula! I love the bitter taste of this green, balanced with the sweet and sour flavor of Parmigiano Reggiano and pine nuts. Pesto Arugula is perfect to toss pasta, but is great also as seasoning of baked or boiled vegetables and chicken or brisket salad. Try it on simply spread on toasted bread as well, it is delicious!
