Crew missing last meal (3)
I believe the answer is:
tea
'meal' is the definition.
(tea is a type of meal)
'crew missing last' is the wordplay.
'crew' becomes 'team' (I've seen this before).
'missing last' means to remove the last letter.
'team' with its last letter removed is 'TEA'.
(Other definitions for tea that I've seen before include "Eg, gunpowder, pekoe" , "Tisane" , "Elevenses" , "leaves much to be desired?" , "Cuppa" .)
