Chosen, though less than delectable (5)
I believe the answer is:
elect
'chosen' is the definition.
('elect' as an adjective can mean chosen)
'less than delectable' is the wordplay.
'less' indicates the answer is hidden within the clue (the clue less some of the letters in it).
'ELECT' can be found hidden inside 'than delectable'.
'though' acts as a link.
(Other definitions for elect that I've seen before include "Choose for Parliament, say" , "Choose by ballot" , "Put in power by voting" , "Preferred" , "Opt for; chosen" .)
