Seasoned, as peanuts (6)
I believe the answer is:
salted
'seasoned as peanuts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for salted that I've seen before include "Like some nuts" , "Seasoned, given piquancy; (of meat) preserved" , "cured" , "Lasted, being preserved" .)
