In a mason jar, mix together lemon zest, lemon juice, olive oil and maple syrup. Drizzle a small amount of vinaigrette over chopped kale. Massage until tender, about 2-3 minutes. Toss into a large bowl.
Add remaining ingredients. Drizzle with desired amount of vinaigrette. Salt and pepper to taste. Serve immediately, or allow to marinate for 1-2 hours.
