This prepares a large salad - great for potlucks, BBQs, or any other family gathering. You can also make it and save leftovers for up to 2 days. If you know ahead of time that you will have leftovers, plan on setting aside a portion without the arugula. The arugula, a leafy green, is the only ingredient that is best enjoyed the day of preparation, especially if it has been mixed with any type of salad dressing or vinaigrette.
