Antipasto tidbit (5)
I believe the answer is:
olive
'antipasto tidbit' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for olive that I've seen before include "Yellowy-green colour and fruit" , "One [TYPE OF TREE] is from the Mediterranean" , "girl" , "This branch is offered in peace gesture" , "Greyish-green; fruit" .)
