Girl throws apes legumes (9)

I believe the answer is:

chickpeas

I'm a little stuck... Click here to teach me more about this clue!

'legumes' is the definition.
(chickpea is a kind of legume)

'girl throws apes' is the wordplay.
'girl' becomes 'chick' (I can't justify this - if you can you should believe this answer much more).
'throws' indicates anagramming the letters.
'apes' anagrammed gives 'peas'.
'chick'+'peas'='CHICKPEAS'

Can you help me to learn more?
