Cheap sort of food (5)
I believe the answer is:
peach
'food' is the definition.
(peach is a kind of food)
'cheap sort' is the wordplay.
'sort' indicates an anagram.
'cheap' with letters rearranged gives 'PEACH'.
'of' acts as a link.
(Other definitions for peach that I've seen before include "Soft fleshy fruit" , "Fruit - beauty" , "Velvety-skinned fruit" , "Cheap (anag.)" , "Sweet stone-fruit" .)
