Method
- Gather and prep everything first: brioche buns, cheddar, mayonnaise and set within reach of the stove.
- Set a wide pan over medium heat and sweat the leeks in a little butter until translucent.
- Turn the heat up, add the mushroom melt, and cook until deeply browned and aromatic.
- Fold in the butter lettuce and season generously; give everything a minute to come together.
- Off the heat, brighten it up with a knob of butter and a final crack of pepper.
- Plate it up while hot and pass extra at the table.
