Five simple ingredients, no chopping (especially if you use bagged baby arugula from the store), and ready in under 10 minutes.  How can you argue with that?  I call this a sophisticatedly simple salad.  It’s definitely quick and easy to make, but that doesn’t mean it lacks in taste.  You’ll find some of the finest restaurants with this on the menu because it holds its own in flavor.  The lemon vinaigrette adds just enough to compliment without competing with arugula’s unique and spicy flavor.  And anytime you freshly shave parmesan it brings out the rich, bold, and complex flavors of the cheese.  Some of the best recipes are no fuss, and this is definitely one of them.  Real food.  Real fast.  But don't rush eating it.  Take your time to savor its flavor!
