Eric prepared some food (4)
I believe the answer is:
rice
'some food' is the definition.
(rice is a food)
'eric prepared' is the wordplay.
'prepared' indicates an anagram.
'eric' with letters rearranged gives 'RICE'.
(Other definitions for rice that I've seen before include "Grains from the paddy field" , "Staple cereal" , "Food crop" , "It grows in paddy-fields" , "Grain from the paddy field" .)
