Bandages are put on salads (9)

I believe the answer is:

dressings

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

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

'put on salads' is the wordplay.
'put on' becomes 'dress' (dressing is a kind of putting on).
'salads' becomes 'ings' (I can't explain this - if you can you should give a lot more credence to this answer).
'dress'+'ings'='DRESSINGS'

'are' is the link.

Can you help me to learn more?

(Another definition for dressings that I've seen is " bandages".)

I've seen this clue in the Sydney Morning Herald.
