Promotional event not providing a meal (5)

I believe the answer is:

lunch

'meal' is the definition.
(lunch is a kind of meal)

'promotional event not providing a' is the wordplay.
'promotional event' becomes 'launch' (eg a product launch).
'not providing' indicates named letters should be taken away.
'launch' with 'a' taken away is 'LUNCH'.

(Another definition for lunch that I've seen is " Midday meal".)

I've seen this clue in The Times.
