Order chaps in some food (7)
I believe the answer is:
spinach
'some food' is the definition.
(spinach is a kind of food)
'order chaps in' is the wordplay.
'order' is an anagram indicator.
'chaps'+'in'='chapsin'
'chapsin' is an anagram of 'SPINACH'.
(Other definitions for spinach that I've seen before include "Vegetable leaves" , "Popeye's vegetable" , "Popeye the Sailor's vegetable of choice" , "something to eat" , "Leaf vegetable" .)
