Food -- some platefuls sent back (4)
I believe the answer is:
feta
'food' is the definition.
(type of cheese)
'some platefuls sent back' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'sent back' is a reversal indicator.
'atef' can be found hidden inside 'platefuls'.
'atef' in reverse letter order is 'FETA'.
(Other definitions for feta that I've seen before include "Goat's or sheep's milk cheese" , "Type of cheese" , "White and salty goat or sheep cheese" , "Greek cheese from goat or sheep milk" , "Soft Greek cheese" .)
