Peter Rabbit Cole Slaw

I love to make this cole slaw in the summer because it is so cool, creamy and a great side dish for fried food. I like to serve it with either fried chicken like I have pictured or with fried shrimp. I gave it this name because every time I make it I think you could find all these things in Mr. McGregor's garden and thats what Peter Rabbit was after.
The cabbage at the store was enormous so I just used half a head but if you find small ones you can use the whole head.
1/2 head green cabbage, sliced
1/2 head purple cabbage, sliced
1 small bunch cilantro chopped, about 1C
1 bunch green onion, about 6
4 carrots slice thinly, I used a mandolin
Enough mayonnaise to coat the slaw, about 11/2-2 C
1 t garlic powder
1/2 t celery salt
Salt and pepper
Mix all the ingredients in a big bowl and chill.
