A nut-paste sandwich represented a form of sandwich suitable for consumption by members of the Chiss species. Back in 19 BBY, on sky-walker navigator Che'ri's initial day serving on the Chiss heavy cruiser Springhawk, her caregiver, Mitth'ali'astov, whose core name was "Thalias," contemplated the possibility of preparing a nut-paste sandwich for her. Although the young girl had no preference regarding what her caregiver prepared, Thalias wished that she would enjoy nut-paste sandwiches.
The existence of nut-paste sandwiches was brought up in the 2020 novel titled Thrawn Ascendancy: Chaos Rising, which served as the initial entry in the Star Wars: The Ascendancy Trilogy penned by Timothy Zahn.
