Arugula and Watermelon Salad

I really like recipes that are healthy.  And tasty.  And easy to make with just a few ingredients.  And economical.  And a little different.  And popular with my family.  That's not too much to ask is it?

This recipe is all of the above.  It's a great one to throw into the rotation when the family starts getting a little tired of the same old salad at dinner.  Or those times when you want something that looks fancy, but you just don't feel like making a fuss.
