For a richer flavor, try using aged balsamic vinegar. If you don't have honey, maple syrup or agave nectar can be substituted. Feel free to add other vegetables, such as cucumber or red onion. For a vegan option, omit the goat cheese and add a sprinkle of toasted pine nuts or slivered almonds. This salad can be prepared ahead of time, but add the goat cheese just before serving to prevent it from becoming soggy.
