As consumed by me and half London (5)

I believe the answer is:

melon

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

'as consumed by' is the definition.
I can't judge whether this definition defines the answer.

'me and half london' is the wordplay.
'and' is a charade indicator (letters next to each other).
'half' indicates taking half.
'london' with half the letters taken is 'lon'.
'me'+'lon'='MELON'

Can you help me to learn more?

(Other definitions for melon that I've seen before include "Fruit - lemon (anag)" , "US profits" , "Eg, cantaloupe, galia" , "Member of the gourd family" , "Sweet juicy fruit" .)

I've seen this clue in the Evening Standard.
