Place shredded brussels sprouts, apple, onion, pecans, and dried cranberries in a large bowl and toss to combine.
Place dressing ingredients in a jar with a lid and shake vigorously to combine. Alternately, you can whisk it together in a bowl, but I really love the mason jar technique.
Pour dressing over the salad and toss well to combine. You will have to toss quite a bit to get it evenly distributed.
Top with blue cheese.
Serve and enjoy!
