Veg on gas uncovered (7)
I believe the answer is:
legumes
'veg on gas' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for legumes that I've seen before include "Peas, beans, and lentils" , "Pulse" , "Plants that bear their seeds in pods" .)
