Ship with cargo of sweet vegetables (5)
I believe the answer is:
Here is my best explanation:
'vegetables' is the definition.
(spud is a kind of vegetable)
'ship with cargo of sweet' is the wordplay.
'ship' becomes 'ss'.
'with cargo of' is an insertion indicator.
'sweet' becomes 'pud' (pud is a kind of sweet).
'ss' going around 'pud' is 'SPUDS'.
