Afternoon snacker's order for something easy, something different (1,5,2,4,3,7,3,2,3)

'afternoon snacker's order for something' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'easy something different' is the wordplay.
I cannot really understand how this works, but
'easy' could be 'pieceofcake' (if something is easy it's a piece of cake) and 'pieceofcake' is located in the answer.
'different' could be 'another' (synonyms) and 'another' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
