"What the devil is this? Green leaves?"
– James T. Kirk, 2266 ("The Corbomite Maneuver")
Dietary salad was a type of salad that facilitated weight loss.
In 2266, Yeoman Janice Rand brought Captain James T. Kirk a serving of dietary salad. This was due to Doctor Leonard McCoy having altered Kirk's diet card due to the captain's having gained two pounds of body weight. She offered to get him something else, but Kirk instead asked her to bring some for McCoy as well. The doctor dodged the offer, saying he never ate before the rest of the crew did.
