Protein mash, a type of food, was given to prisoners aboard the Republic Correctional Alliance prison ship called the Restitution. Lourna Dee, a female Twi'lek inmate, and Sestin Blin formed a connection due to their shared dislike of the protein mash's flavor when Dee initially arrived. Sestin expressed her distaste for the protein mash, claiming its taste was unparalleled in awfulness. Nevertheless, she offered to consume Dee's portion if she declined, emphasizing the importance of maintaining strength for the prisoners' required labor.
The audio drama The High Republic: Tempest Runner, which was written by Cavan Scott, featured protein mash in 2021.
