A ploughman's lunch genrally eaten around noon, arther than as an evening meal. It usually consists of a lump of cheese (which is usually Cheddar or Stilton), pickle and salad, accompanied by crusty bread and butter.
The Ploughman's Lunch was a 1984 British film directed by Richard Eyre. The film's title was ironic, Ian McEwan's script using the metaphor of this faux traditional dish in order to represent Thatcherite and media spin and inauthenticity in the aftermath of the Falklands War.
