One serving cooked meal: it's eaten very warm (6,6)

I believe the answer is:

maitre dhotel

'one serving' is the definition.
(a maitre d'hotel is a head waiter)

'cooked meal it's eaten very warm' is the wordplay.
'cooked' indicates anagramming the letters.
'eaten' is an insertion indicator (some letters have eaten others).
'very warm' becomes 'redhot'.
'meal'+'it'='mealit'
'mealit' anagrammed gives 'maitel'.
'maitel' placed around 'redhot' is 'MAITRE DHOTEL'.

(Another definition for maitre dhotel that I've seen is " Head waiter or steward".)

I've seen this clue in The Times.
