For an extra layer of flavor, consider grilling the eggplant slices before baking. This will add a smoky char that complements the other ingredients beautifully. Feel free to adjust the amount of sun-dried tomatoes, pine nuts, and cilantro to your personal preference. This dish is best served at room temperature, allowing the flavors to meld together. Prepare it ahead of time for easy entertaining. If you don't have pine nuts, slivered almonds or chopped walnuts make a great substitute.
