Prep: 7 minutesThis simple Italian salad is beautiful and fast to assemble. Its success depends wholly on using top-quality fresh ingredients. We used a combination of red and yellow tomatoes for added color. Make the salad extraspecial with heirloom tomatoes, when available. At first glance, one might think that the vinegar has been accidentally omitted; however, this salad traditionally has no vinegar at all. Serve with toasted baguette slices, if desired.
