Where one might find pâté de foie gras without much difficulty? (2,1,5)
I believe the answer is:
on a plate
I believe this clue is a double definition.
'where one might find pate de foie gras' is the first definition.
(pate de foie gras is a type of food)
'without much difficulty?' is the second definition.
(as in being handed something on a plate)
(Other definitions for on a plate that I've seen before include "with little effort" , "Available without effort - dinner?" , "Informally available without effort - a meal?" , "requiring next to no effort" , "readily available" .)
