Prepare the dressing by whisking together olive oil, lemon juice, garlic, maple syrup, and salt in a medium bowl and set aside.
In a large bowl, toss together shredded brussels sprouts and kale mixture with your hands. Slowly pour in the dressing and use your hands to massage into the kale and brussels sprouts for about 5 minutes. Let sit for 10 minutes.
Next, toss in apple slices, dried cranberries, and chopped nuts. Top with vegan feta, and with freshly ground black pepper.
