Omelet need (3)
I believe the answer is:
egg
'omelet need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for egg that I've seen before include "Quiche ingredient" , "It may be poached" , "Urge on the breakfast dish" , "One beaten by a whisker perhaps" , "nit? Just a bit!" .)
