Melon

A melon is a fruit consumed primarily by humans, but Kig-Yar appear to like the fruit as well. It grows on plants indigenous to Earth.

Harvest colony grows melons using transplanted seeds from Earth. A shipment of melons from Harvest to Madrigal aboard the freighter Horn of Plenty suffered a slipspace drive malfunction in 2524, fatefully placing it in range of a Covenant Kig-Yar ship, which boarded the vessel, sampled some of the melons, and destroyed the ship, fatefully making it first contact between humans and Covenant species, sparking the Human-Covenant War.
