Time to dine on stews (8)
I believe the answer is:
noontide
'time' is the definition.
(noontide is a kind of time)
'to dine on stews' is the wordplay.
'stews' is an anagram indicator.
'to'+'dine'+'on'='todineon'
'todineon' with letters rearranged gives 'NOONTIDE'.
(Other definitions for noontide that I've seen before include "Midday" , "Time" , "lunchtime? Certainly" , "12" .)
