Meal -- I get it cooked, OK? (10)
I believe the answer is:
legitimate
'ok?' is the definition.
(I've seen this before)
'meal i get it cooked' is the wordplay.
'cooked' indicates anagramming the letters.
'meal'+'i'+'get'+'it'='mealigetit'
'mealigetit' with letters rearranged gives 'LEGITIMATE'.
(Other definitions for legitimate that I've seen before include "It's admissible" , "Kosher" , "authorised" , "Within the rules" , "Conforming to the law" .)
