Rummage among model vegetables (5)
I believe the answer is:
delve
'rummage' is the definition.
(I've seen this before)
'among model vegetables' is the wordplay.
'among' says the answer is hidden in the clue.
'DELVE' can be found hidden inside 'model vegetables'.
(Other definitions for delve that I've seen before include "Dig - rummage" , "Burrow" , "Dig - research deeply" , "Search deeply for information" , "Make painstaking enquiries (into something)" .)
