Waitrose mexican slaw

Hello, does anyone know the syn value of this? It's a pot of salad with a small tub of dressing.
Thanks!

Most salad ingredients are free, indeed superfree, but without knowing what is in it, one can't be sure.

Does the dressing have a calorie count on it? If so, the 1 syn per 20 calories would apply.

Thanks for replying. Only the whole calorie content was on the box including for the salad. I've counted it as 4 syns to be on the safe side.
