Maker of all my sandwiches put away on launch of restaurant (7)

Ross

I believe the answer is:

creator

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

'maker' is the definition.
(I've seen this before)

'of all my sandwiches put away on launch of restaurant' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
'away' could be 'a' (abbreviation as used in sports fixtures) and 'a' is found in the answer.
'on' could be 're' (regarding) and 're' is present in the answer.
The remaining letters 'ctr' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for creator that I've seen before include "The Almighty" , "Someone who makes something" , "Person who makes or invents things" , "Originator - God" , "Inventor" .)
