Food -- good spread (4)
I believe the answer is:
grub
'food' is the definition.
(grub is a kind of food)
'good spread' is the wordplay.
'good' becomes 'g' (abbreviation).
'spread' becomes 'rub' (I've seen this in other clues).
'g'+'rub'='GRUB'
(Other definitions for grub that I've seen before include "Gentle, food" , "ferret > eats" , "Caterpillar - food" , "Dig - maggot - food" , "Beetle larva" .)
