Provide the food for (5)
I believe the answer is:
cater
'provide the food for' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cater that I've seen before include "Provide food etc" , "Make provision for" , "Provide food and drink (for an event)" , "Supply food for parties" , "Trace in order to serve" .)
