Dice pre-cooked shrimp (peeled and de-veined, of course!) into bite sized pieces, discarding the tail. Place slaw and shrimp into a large bowl. In a small bowl, add the vinegar, oil, soy sauce, ginger, juice of the lime, salt and pepper. Whisk or stir well until combined. Pour dressing over slaw and toss to coat evenly. Cover and refrigerate for at least one half hour for flavors to fully combine. Serve chilled.
