Bring brown and wild rice blend, water, orange juice, and salt to a boil in a saucepan. Reduce heat to medium-low, cover, and simmer until rice is tender, 30 to 45 minutes. Drain excess liquid, fluff rice with a fork, and cook, uncovered, for 5 minutes more. Remove from heat and let cool, 20 to 30 minutes.
Combine agave nectar, olive oil, and apple cider vinegar in a small bowl for the dressing.
Add dressing, kale, bell pepper, pine nuts, grapes, celery, parsley, basil, and lemon zest to the cooled rice and mix well. Refrigerate for 1 hour before serving.
