Preferring meat, one makes awful toast (5)
I believe the answer is:
stoat
'preferring meat one' is the definition.
I can't judge whether this defines the answer.
'awful toast' is the wordplay.
'awful' indicates anagramming the letters.
'toast' anagrammed gives 'STOAT'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for stoat that I've seen before include "Source of ermine" , "Eating rabbit, he" , "European ermine" , "Small carnivorous mammal of the weasel family" , "Provider of ermine" .)
