Meanwhile, heat oil in a skillet over medium-high heat. Add shallot, ginger, garlic and turkey, stirring to crumble turkey. Stir in fish sauce, coconut sugar and red pepper flakes. Cook 3-4 minutes, or until turkey is browned. Add 2-3 tablespoons ramen cooking water and eggplant, scraping the pan to loosen any browned bits. Add drained noodles, zest and juice of ½ lime, tossing to coat. Add more ramen cooking water, a few tablespoons at a time so the mixture is well coated and slightly saucy, but not soupy.
