Notes

  • Use thawed and well-drained frozen spinach if fresh is unavailable.
  • Low-moisture shredded mozzarella melts best and holds filling together.
  • Add sun-dried tomatoes or olives for extra Mediterranean flavor.
  • Include grilled chicken or chickpeas for added protein.
  • Reheat in a skillet or oven to maintain crispness; avoid microwaving if possible.
  • Store leftovers in the refrigerator for up to 3 days.
