- "Uh, I missed lunch. So, I'm going to fix myself a sandwich. Anyone want anything? Anyone?"
- ―Rodney McKay
A sandwich is a type of food from Earth, which combines certain vegetables, meats, sauces, and or cheeses between two slices of bread. Ham, Turkey, Tuna, Roast beef and Peanut butter are popular sandwiches.
In 2004, Major Samantha Carter packed several sandwiches (including Teal'c's favorite, turkey) for her and Teal'c's voyage to contact the Asgard in the Othala galaxy. (SG1: "New Order, Part 1")
In 2006, after the Battle of P3Y-229, Kvasir and Lt. Colonel Cameron Mitchell tested the Odyssey's Asgard transporter by beaming a sandwich, to check if the transporter had been repaired properly. (SG1: "Flesh and Blood")
Later that same year, Dr. Rodney McKay made a remark that one of the Odyssey's crew members didn't allow him to finish his sandwich in the ship's corridors. (SG1: "The Pegasus Project")
Pre-packed sandwiches are often served in the Atlantis Mess hall. (SGA: "Brain Storm")
