Canapé

A canapé was an appetizer consisting of a piece of bread or toast or a cracker topped with a savory spread.

In 2370, Rom scanned several canapés in Club Martus with a tricorder, suspecting that Quark may have contaminated them as a move against his rival, Martus Mazur. 

In 2371, Miles O'Brien served canapés which he apparently made himself as part of his romantic dinner with his wife. 

In 2373, canapés were served at Ahni Jetal's birthday party on the USS Voyager.
