Mince pasty I'd stuffed with nothing in awful state (8)
I believe the answer is:
dystopia
'awful state' is the definition.
(an awful or horrible state or society)
'mince pasty i'd stuffed with nothing' is the wordplay.
'mince' indicates anagramming the letters.
'stuffed with' indicates putting letters inside (some letters get stuffed inside).
'nothing' becomes 'O' (looks like zero - 0).
'pasty'+'id'='pastyid'
'pastyid' anagrammed gives 'dystpia'.
'dystpia' placed around 'o' is 'DYSTOPIA'.
'in' acts as a link.
(Other definitions for dystopia that I've seen before include "Imaginary society in which everything is bad" , "there's no worse place" , "worst possible place?" , "Imaginary place of maximum badness" , "Undesirable place" .)
