Food in bags to carry out (9)

Ross

I believe the answer is:

takeaways

'food' is the definition.
(takeaway food)

'bags to carry out' is the wordplay.
'bags' becomes 'takes' (bag can mean to take or obtain).
'to carry' means one lot of letters goes inside another.
'out' becomes 'away' (similar in meaning).
'takes' enclosing 'away' is 'TAKEAWAYS'.

'in' is the link.
