Chances of hummus being dished up? About the same (4,2,1,8)

I believe the answer is:

much of a muchness

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

'the same' is the definition.
I can't tell whether this defines the answer.

'chances of hummus being dished up?' is the wordplay.
'being dished up?' is an anagram indicator.
'chances'+'of'+'hummus'='chancesofhummus'
'chancesofhummus' is an anagram of 'MUCH OF A MUCHNESS'.

'about' acts as a link.

Can you help me to learn more?
