This breakfast food is typical of Shuttle-era menu choices. As there is no onboard refrigerator or freezer, most foods are processed for storage at room temperature. Single servings are packaged in disposable plastic containers, pop-top cans, or foil pouches, and foods are eaten directly from these containers. Dehydrated food items like this have a circular port in one corner for adding water to make the food edible. This item was returned from the STS-27 Space Shuttle mission (Atlantis) in 1988.
