Veggie in a pod (3)
I believe the answer is:
pea
'veggie in a pod' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pea that I've seen before include "Small vegetable" , "It may climb frame" , "Cause of a princess's insomnia?" , "Edible seed from pod" , "Legume" .)
