I leave the peel on my apple I like the red in the salad.
Use a store bought dressing if you wish.
This dressing mix is sweet enough for us but it may not be for others, add more of each ingredient until you are happy with the outcome. Taste it. Less milk if you like a thicker dressing and more milk if you don't.
Add sliced or chopped capsicum.
With the apple included this sweetens the cabbage so you use less sugar in your dressing.
Mix your cabbages.
If you are taking out or wish to serve later in the day prepare it all excluding the apple, chop when needed add to salad, then add the dressing.
