Dish covered in handsome lettering (8)
I believe the answer is:
omelette
'dish' is the definition.
(I know that Omelette is a type of dish)
'covered in handsome lettering' is the wordplay.
'covered in' says the answer is hidden in the clue.
'OMELETTE' is hidden within 'handsome lettering'.
(Other definitions for omelette that I've seen before include "Dish made of eggs and filling" , "Broken-egg dish" , "A capsicum pod" , "Dish of cooked beaten eggs" , "You can't make one without breaking eggs" .)
