Ready to be eaten (4)
I believe the answer is:
ripe
'ready to be eaten' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ripe that I've seen before include "Fully developed, ready to be eaten" , "Opportune" , "Pier (anag.)" , "Ready for harvesting, in its prime" , "Mature for eating like fruit" .)
