Vegetable lover, scram! (9)
I believe the answer is:
mangetout
'vegetable' is the definition.
(I've seen this before)
'lover scram' is the wordplay.
'lover' becomes 'man' (male lover).
'scram' becomes 'get out' (both can mean 'go away!').
'man'+'getout'='MANGETOUT'
(Other definitions for mangetout that I've seen before include "Edible pea pods" , "Type of pea" , "vegetables" , "Sugar peas" , "From this pod" .)
