What is a refreshing summer salad I can whip up for a 4th of July get-together?

A lunchtime Summer Sorghum Salad with Watermelon, Feta and Tomatoes is most enticing when the temperature rises. The combination of sorghum, arugula, watermelon, feta cheese and tomatoes makes this dish stand out from the lettuce, carrots and cucumber crowd. The recipe includes vinaigrette with just a touch of maple syrup.
