Poke bowl topping (3)
I believe the answer is:
roe
'poke bowl topping' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roe that I've seen before include "Hoofed animal(s)" , "A mass of fish-eggs" , "Food from fish" , "eg Caviare" , "Fish eggs; small deer" .)
