For a start, you can mince them! (5)
I believe the answer is:
tarts
'can mince them' is the definition.
I can't tell whether this definition defines the answer.
'for a start' is the wordplay.
'start' anagrams to 'TARTS'.
However, I'm unsure how the anagram is indicated.
'you' is the link.
Can you help me to learn more?
(Other definitions for tarts that I've seen before include "women (that may be offensive)" , "Small open pies" , "Pastry cases with fillings" , "Broads" , "Flans" .)
