Cucumber gave this salad nice color and crunch, but 2 cups cubed honeydew can be substituted. We liked the subtle flavor of light agave in the dressing; a mild honey, such as clover honey, also works. If queso fresco is not available, use feta but omit the ½ teaspoon salt used to season the cheese. The dressing can be made and the melons and cucumber prepped a few hours in advance, but don't toss the salad more than 30 minutes before serving. This recipe is easily doubled.
