Vegetarian food — way to live during embargo (5,4)
I believe the answer is:
broad bean
'vegetarian food' is the definition.
(food suitable for vegetarians)
'way to live during embargo' is the wordplay.
'way' becomes 'road' (road is a kind of way).
'to live' becomes 'be' (synonyms).
'during' is an insertion indicator.
'embargo' becomes 'ban' (a ban on trade).
'road'+'be'='roadbe'
'roadbe' going inside 'ban' is 'BROAD BEAN'.
(Other definitions for broad bean that I've seen before include "Green vegetable" , "plant" .)
