Rustic worker after vegetables (7)
I believe the answer is:
peasant
'rustic' is the definition.
(peasant is a kind of rustic)
'worker after vegetables' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'after' means one lot of letters go next to another.
'vegetables' becomes 'peas' (I've seen this before).
'ant' put after 'peas' is 'PEASANT'.
(Other definitions for peasant that I've seen before include "Poor farmworker" , "Lowly tiller of land" , "Member of rural underclass" , "Revolting person" , "Provincial" .)
