The Reuben's origin story is disputed — a grocer in Omaha named Reuben Kulakofsky or a New York deli owner in the 1910s — but everyone agrees on the formula: corned beef, sauerkraut, Swiss cheese, and Russian dressing, griddled between rye slices until the cheese melts into every corner. It's the definitive deli sandwich, and it's impossible to eat just one half.
