# Expert Advice:

01 -
  • The pesto adds an herby brightness that cuts through all that rich melted cheese
  • It takes eighteen minutes from start to finish including slicing and plating
  • One bite transforms a childhood lunch into something you'd actually serve guests
02 -
  • Medium heat might feel too slow but going higher will burn the bread before the cheese melts
  • Pressing gently with your spatula helps the bread make contact with the pan for even browning
03 -
  • Mayo instead of butter on the outside creates an even crisper golden crust
  • Let the cheese come to room temperature before assembling for faster melting
