Bacon pieces, for example, in quiche with no topping (3)
I believe the answer is:
art
'bacon pieces for example' is the definition.
(Francis Bacon was an artist)
'quiche with no topping' is the wordplay.
'quiche' becomes 'tart'.
'with no topping' means to remove the first letter.
'tart' with its initial letter taken off is 'ART'.
'in' is the link.
(Other definitions for art that I've seen before include "Beautiful or significant products of human creativity" , "Works of creative imagination" , "Lovely piece of work" , "''... is long and life is short''" , "Skill in a specified thing" .)
