Chopped into small cubes (5)
I believe the answer is:
diced
'chopped into small cubes' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for diced that I've seen before include "Cubed" , "Cut into small cubes" , "Played with small cubes" , "Chopped; gambled" , "Risked" .)
