Any salsa is best when served fresh. If it isn't convenient to make the salsa just before serving time, prepare and refrigerate all your ingredients ahead of time and toss together 15 minutes before serving. It sparkles! In a large bowl, combine all ingredients except cilantro. Toss together. Refrigerate, covered, for up to 2 hours. Just before serving, toss with cilantro. Yield: about 4 cups.
