vegetables

I'm a little stuck... Click here to teach me more about this clue!

'corrupted? they could be roasted' is the definition.
The definition suggests an adverb but the answer is not.

'vets eg able to be' is the wordplay.
'to be' indicates an anagram.
'vets'+'eg'+'able'='vetsegable'
'vetsegable' anagrammed gives 'VEGETABLES'.

Can you help me to learn more?

(Another definition for vegetables that I've seen is " Edible plants".)

I've seen this clue in The Guardian.
