Fresh summer greens and bits of sweet red pepper dot rice the color of a sunset — this is one good-looking salad to bring to the table, or to pack away for a picnic. In fact, I first tasted it when a Spanish friend brought it to one of our “Shakespeare in the Park” picnics in New York. It’s indestructible enough to go almost anywhere. Can be made hours ahead and chilled, but serve the salad at room temperature.
