Krellan food was a type of cuisine.

When Flith suggested he and Liam Bilby have Krellan food, Bilby declined, saying the last time he had some it gave him heartburn. (DS9: "Honor Among Thieves")

The Star Trek Encyclopedia (4th ed., vol. 1, p. 444) mentioned that the Krellans were a civilization and that Nozala sandwiches were Krellan food.
