Dressing, invite great chaos (11)
I believe the answer is:
vinaigrette
'dressing' is the definition.
(I know that vinaigrette is a type of dressing)
'invite great chaos' is the wordplay.
'chaos' indicates an anagram.
'invite'+'great'='invitegreat'
'invitegreat' with letters rearranged gives 'VINAIGRETTE'.
(Other definitions for vinaigrette that I've seen before include "Salad dressing" , "that will be put on the table in France" , "French dressing" , "sharp dressing" .)
