# Expert Advice:

01 -
  • Everything comes together in one pan, meaning less cleanup and more time to actually enjoy your meal

  • Dont crowd the pan when cooking mushrooms or they'll steam instead of brown, losing that wonderful depth of flavor
  • Adding spinach last and cooking it briefly keeps it bright and prevents the entire dish from becoming watery

  • Toasting your pine nuts in a dry pan for just 2 minutes before garnishing adds incredible depth and crunch
  • Reserve a handful of fresh spinach to add at the very end for contrasting texture and color
