Ser pan comido

Literally: To be eaten bread

Example: “Con este mapa, llegar al pueblo es pan comido.” — With this map, getting to the village is a piece of cake.

English equivalent: A piece of cake

Origin: The exact origin isn't documented, but the phrase is generally traced to medieval Spain, when bread was the most basic and universally available staple food — genuinely one of the easiest things a person could eat, requiring no skill, tools, or particular effort. A related, older Spanish saying is already on record by the 1300s: el pan comido, la compañía deshecha (once the bread is eaten, the company breaks up), describing companionship that dissolves the moment its practical purpose ends. The specific modern sense of pan comido for something effortlessly easy is generally dated to the 1800s, evolving gradually out of that older saying's shared imagery of bread as the plainest, least demanding food available.
