Put the Brussels sprouts, apple and scallion in a large bowl. Set aside.
1 lb Brussels Sprouts shredded, 1 Granny Smith Apple cut into thin strips, 5 scallions chopped - green tops only
In a smaller bowl whisk the lemon juice, lemon zest, maple syrup, apple cider vinegar, mustard and olive oil with a pinch of salt and pepper to make the dressing.
juice of 1 lemon plus some of the zest, 1 tablespoon maple syrup, 1 tablespoon apple cider vinegar, 1 tablespoon coarse ground dijon mustard, 2 tablespoon, Kosher salt and black pepper
Pour the dressing over the vegetables and toss to coat. Refrigerate for at least 10 minutes to chill and give the flavors time to merge.
Notes
We used this slaw as a topping for fish tacos but it makes a great side on its own or with some minor additions (like nuts or chicken) a fabulous main course.
I used a granny smith but I really think any apple would be just fine.
