Crossword Genius

Where you might find sandwiches etc a disaster, lacking in taste (10)

Ross

I believe the answer is:

indelicate

'lacking in taste' is the definition.

I cannot understand how the remainder of the clue works.

(Other definitions for indelicate that I've seen before include "Practised (a play)" , "Saucy" , "lacking taste" , "Rather rude" , "Coarse" .)

I've seen this clue in The Independent.
