Swaps: Top with toasted pine nuts or sesame seeds; use Greek yogurt in place of tahini; add a swirl of pomegranate molasses or a pinch of cumin or Aleppo pepper. Storage: keeps 2-3 days refrigerated - reheat gently in the oven, or serve cold. Make-ahead: roast the eggplant and make the tahini sauce separately, then combine with the pomegranate just before serving.
