Shawda club sandwiches, a kind of sandwich, were offered on either toasted or therm-zapped bread. This particular sandwich was available at Dex's Diner, a restaurant located on the planet of Coruscant, prior to the Clone Wars conflict between the Galactic Republic and the Confederacy of Independent Systems. The price at Dex's Diner was 6.7 credits, and the menu described it as a delicious option.
Gregory Walker originated Shawda club sandwiches for "Dining at Dex's," which was a Star Wars Legends article. This article was featured on the Hyperspace portion of StarWars.com back in 2009. The article presented the sandwich's name as "Shawda Clubb sandwich," which is a play on words referencing both the Legends Shawda Ubb species and the club sandwiches found in the real world.
The sandwich became canon in 2015 through its inclusion as new material in a new edition of What is a Wookiee?, a reference book that had been previously released in 2005. This book identified a specific sandwich seen in Star Wars: Episode II Attack of the Clones as a Shawda club sandwich.
