May return some food (3)
I believe the answer is:
yam
'some food' is the definition.
(yam is a kind of food)
'may return' is the wordplay.
'return' is a reversal indicator.
'may' in reverse letter order is 'YAM'.
(Other definitions for yam that I've seen before include "vegetable plant" , "May be a sweet potato" , "Tuberous vegetable" , "Tropical climber" , "Potato-like vegetable" .)
