Once you have the cabbage, carrot and onion shredded/cut up, then it's a matter of mixing everything together except for the dressing. Put the cabbage, carrot, onion and craisins in a medium bowl.

In a 1 cup measuring cup or small bowl, mix the Miracle Whip (or mayonnaise), milk, sugar, salt and pepper until smooth. Taste it. The dressing should be slightly sweet and salty. You can add more seasonings, a tiny bit at a time, mixing thoroughly until it is the taste you like.

Pour the dressing over the vegetables and mix to thoroughly coat.

Refrigerate until serving.
