"All sliders are served with our special garnish. Sernpidalian mayo-ketchup and Bimm mustard available upon request."
―The Dex's Diner menu[src]

Mustard was an edible item that was served in Dex's Diner as a side order with any sliders, before its destruction in 19 BBY. Varieties included Bimm mustard and Boontaspiced mustard.

Behind the scenesEdit

Mustard is mentioned in a Hyperspace-exclusive release, Dining at Dex's by Gregory Walker, which represents the in-universe menu of Dex's Diner. In real life, mustard is a popular condiment made from the ground seeds of mustard plants.
