Spaghetti with Arugula Pesto, Golden Beets, Goat Cheese and Toasted Walnuts

This spaghetti is a play on the delicious (if not a little tired and redundant!) Beet salad. You know the drill, it is on every menu in the world- A beet salad served on a bed of arugula with crumbled goat cheese and toasted walnuts. Such an excellent combination of flavors and textures. But I thought that this pasta dish was a way to take the same flavors and make them new again.
