The Reuben is also a familiar deli sandwich in Canada, especially in urban restaurants and Jewish delicatessens.

Ingredients and preparation

A standard Reuben uses corned beef, Swiss cheese, sauerkraut, and Russian or Thousand Island dressing on rye bread. It is typically grilled or toasted so the bread crisps and the cheese melts.
