Provide food consumed in Costa Rica (5)
I believe the answer is:
cater
'provide food' is the definition.
(I've seen this before)
'consumed in costa rica' is the wordplay.
'consumed' becomes 'ate' (eating is a kind of consuming).
'in' indicates putting letters inside.
'costa rica' becomes 'cr'.
'ate' going within 'cr' is 'CATER'.
(Other definitions for cater that I've seen before include "provide meals" , "... you'll see minister" , "Trace in order to serve" , "Supply food for parties" , "Provide food etc" .)
