Food provided by an automaton
I believe the answer is:
tomato
'food' is the definition.
(tomato is a kind of food)
'provided by an automaton' is the wordplay.
'provided by' indicates the answer is hidden within the clue (the answer is provided within the clue).
'TOMATO' is hidden in the letters of 'automaton'.
(Other definitions for tomato that I've seen before include "that's suitable to eat" , "Type of sauce" , "Part of a BLT sandwich" , "A motto turned out to be fruit/veg" , "It used to be call a love-apple" .)
