Storage & Freezing Tips

  • Refrigerator: Store in an airtight container for up to 2 days. Keep the components separate if possible to preserve texture.
  • Reheating: Reheat gently in a skillet on medium-low heat with a splash of olive oil or butter.
  • Freezing: Freezing is not recommended for this dish because ingredients like spinach become soggy, rubbery, or mushy when defrosted.
