I'm a little stuck... Click here to teach me more about this clue!

'something to eat' is the definition.
(fig is a kind of food)

I don't understand the remainder of the clue.

(Other definitions for fig that I've seen before include "Fruit with many seeds" , "This tree's leaf may cover nudity" , "Sweet fleshy fruit, often dried" , "Tree whose leaf may cover nudity" , "Soft sweet fruit of broad-leaved tree" .)

I've seen this clue in the Evening Standard.
