Vinaigrette (6,8)
I believe the answer is:
french dressing
'vinaigrette' is the definition.
(synonyms)
This is the entire clue.
(Other definitions for french dressing that I've seen before include "Saucy embellishment" , "sauce for salad" , "Something going on salad" , "Maybe relish" , "vinaigrette!'" .)
