Make mincemeat out of one submissive turning up (5)

I believe the answer is:
keema
'make mincemeat out' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'one submissive turning up' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'submissive' becomes 'meek' (I've seen this before).
'turning up' is a reversal indicator.
'a'+'meek'='ameek'
'ameek' reversed gives 'KEEMA'.
'of' is the link.
