The easy answer to what to have for dessert (3)
I believe the answer is:
pie
'dessert' is the definition.
(pie is an example of a dessert)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pie that I've seen before include "welcome luxury" , "Pastry product" , "Cooked food" , "Crusty dish" , "Slapstick missile" .)
