Served up sample of spaghetti meals to give out (4)
I believe the answer is:
emit
'give out' is the definition.
(I've seen this before)
'served up sample of spaghetti meals' is the wordplay.
'served up' is a reversal indicator.
'sample of' indicates a hidden word (I've seen this in other clues).
'time' can be found hidden inside 'spaghetti meals'.
'time' backwards is 'EMIT'.
'to' is the link.
(Other definitions for emit that I've seen before include "Give off or discharge" , "Give off, gas say" , "Sent" , "Send forth" , "Release" .)
