Drunkards find room inside for vegetables (8)
I believe the answer is:
shallots
'for vegetables' is the definition.
(I've seen this before)
'drunkards find room inside' is the wordplay.
'drunkards' becomes 'sots' ('sot' can be a synonym of 'drunkard').
'find room' becomes 'hall' (I am not sure about this - if you are sure you should believe this answer much more).
'inside' is an insertion indicator.
'sots' enclosing 'hall' is 'SHALLOTS'.
Can you help me to learn more?
(Other definitions for shallots that I've seen before include "Small onion species" , "in the allotment" , "Small, mild-flavoured, onion-like bulbs" , "Species of small onions" , "Onion-like plants with clusters of bulbs" .)
