Vegetarian food we have as long as we live (5)
I believe the answer is:
pulse
'vegetarian food' is the definition.
(I know that pulse is a type of vegetable)
'we have as long as we live' is the wordplay.
I cannot quite understand how this works, but
'long' could be 'l' and 'l' is found in the answer.
'we' could be 'us' and 'us' is found in the remaining letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pulse that I've seen before include "Bustle" , "Rhythmic beat" , "A vital sign turning" , "Pound" , "Heart rate" .)
