Tofu cooked with pesto is incongruous (3-2-4)
I believe the answer is:
out-of-step
'incongruous' is the definition.
(thesaurus)
'tofu cooked with pesto' is the wordplay.
'cooked with' indicates anagramming the letters (letters cooked into a new form).
'tofu' with its letters mixed up with 'pesto' can make 'OUT OF STEP'.
'is' acts as a link.
(Other definitions for out-of-step that I've seen before include "Not in conformity" , "Different, not aligned with others - on march?" , "Not in harmony or not synchronised with" .)
