Antipasto morsel (5)
I believe the answer is:
olive
'antipasto morsel' 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 "Mediterranean tree-fruit, nice in cocktail" , "I love this fruit" , "Green shade; its branch for peace" , "Type of green" , "Girl's name; tree" .)
