Cucumber sandwich
A cucumber sandwich was a sandwich type of British origin, made out of bread and cucumber.

Within the holoprogram Janeway Lambda One, Henry Burleigh appreciated cucumber sandwiches with his tea, but his sister Beatrice did not as she didn't like the way Cook cut them. 

When experiencing visions caused by the Botha in 2372, Kathryn Janeway falsely thought that Neelix had prepared cucumber sandwiches for Lieutenant Hargrove, but the Talaxian did not even know what cucumber sandwiches were. ()
