Cook some quiche — fabulous (4)
I believe the answer is:
chef
'cook' is the definition.
(both can mean someone who cooks)
'some quiche fabulous' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CHEF' is hidden in the letters of 'quiche fabulous'.
(Other definitions for chef that I've seen before include "Chief male cook in restaurant" , "who has a set of knives?" , "Originator of courses" , "One who prepares courses" , "Principal cook" .)
