Heated chow, perhaps? (3,3)
I believe the answer is:
hot dog
'heated chow perhaps?' is the definition.
I can't tell whether this definition defines the answer.
'heated chow perhaps?' is the wordplay.
'heated' becomes 'hot' (synonyms).
'chow perhaps?' becomes 'dog' (chow is a kind of dog).
'hot'+'dog'='HOT DOG'
(Other definitions for hot dog that I've seen before include "Sausage in breae roll" , "Meat in roll" , "Sausage in a roll for feverish canine" , "'Frankfurter in a bun (3,3)'" , "One panting" .)
