'mistakes when' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'tofu with last of nuts' is the wordplay.
'with' is a charade indicator (letters next to each other).
'nuts' indicates anagramming the letters (nuts can mean crazy).
'last'+'of'='lastof'
'tofu' put after 'lastof' is 'lastoftofu'.
'lastoftofu' with letters rearranged gives 'FOOT FAULTS'.

'serving' acts as a link.
