Empty tuna into a bowl and mix in the marinade until tuna is completely moist, add more if necessary.
In a separate and bigger bowl empty the cabbage or broccoli mixture.
Now combine the tuna mixture with the coleslaw and add in the 1/2 cup of salad dressing. At the same time add in the dried cranberries and the nuts. Mix well until everything is coated with the dressing. This serves about 4-6 people as a side dish or an alternative to salad.
