Ration kit

"How you get so big, eating food of this kind?"

- Yoda to Luke

Ration Kits are survival design for crashed Pilots. They contain a series of preserved edibles with necessary amounts of nutritional substance for an individual's diet. During Luke Skywalker's visit to Dagobah, he was eating a ration bar from his kit when he encountered the hermit, Yoda. Yoda then took a bite from Luke's ration, much to his annoyance.
