'you'll need it for the roast' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'turn the veg on dear' is the wordplay.
'turn' is an anagram indicator.
'dear' becomes 'love' (synonyms).
'veg'+'on'='vegon'
'vegon' anagrammed gives 'oveng'.
'oveng'+'love'='OVEN GLOVE'

'and' acts as a link.

Can you help me to learn more?
