Delmonico cheesesteak

Place the steaks on a sheet of parchment paper and freeze 30 to 40 minutes, until the first centimetre or two is nearly frozen but the meat is not frozen through.

Shave the firm steak into very thin pieces.

Cook the shaved steak hot and fast in a non-stick pan with a little fat until it takes on colour, then flip.

Add a splash of water to steam and melt the cheese over the meat, and gather it into a sandwich shape.

Dress the roll with mayo and shimmy the meat and cheese into it.
