Lorvan cracker
Lorvan crackers were a snack food served at Quark's on Deep Space 9. 

When Doctor Julian Bashir diagnosed Major Kira Nerys with being overworked and suffering from extreme  and borderline exhaustion in 2371, he offered her Karvino juice, Lorvan crackers, a holosuite program, a Jumja stick and gambling tokens. Kira was told she had to enjoy two of the offers before she was allowed to leave Quark's establishment. ()
