Chop cabbage, carrot and onion into very small pieces, set aside.
In large bowl, combine remaining ingredients and beat until smooth.
Add slaw and mix well.
Cover and refrigerate for at least 2 hours before serving. (Don't skip this step, the flavor needs time to set into the slaw).
BTW, I like to make the dressing up and keep it in a squirt bottle in the fridge. When I use it, I have to microwave it a little to thin the honey, but it works since I always refrigerate the slaw before eating anyway.
Also, when we're dieting, I use less than half the dressing and it's still quite good!
