Edible spheroids (4)
I believe the answer is:
peas
'edible spheroids' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peas that I've seen before include "Fruits of the genus Pisum" , "Vegetables from pods" , "Petits pois" , "Edible seeds" , "Legumes" .)
