A salad of shredded cabbage, mayonnaise, carrots, onions, etc (8)
I believe the answer is:
coleslaw
(Other definitions for coleslaw that I've seen before include "accompaniment to Salad Days?" , "We locals consume shredded cabbage and carrots with dressing" , "We locals consume salad of shredded cabbage, carrot and dressing" , "plant-based food" , "healthy food" .)
