Pricey spread (6)
I believe the answer is:
caviar
'pricey spread' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for caviar that I've seen before include "posh meal" , "dear thing" , "produce of Russia?" , "Sturgeon delicacy" , "Salted roe of sturgeon" .)
