Preheat the oven to 400 degrees. Toss the chickpeas with the olive oil, salt, pepper, garlic powder and paprika. Spread them out in an even layer on a large baking sheet and roast for 20-25 minutes, until golden brown and crispy.
While the chickpeas are roasting, make the dressing. Drain the soaking water from the cashews (if you soaked them), then add all of the dressing ingredients to a blender. Blend until smooth and creamy, you may have to scrape the sides halfway through.
When the chickpeas come out of the oven, set them aside to cool for a few minutes.
To assemble the salad, add the prepped kale and spinach to a large serving bowl. Carefully pour the dressing over the greens and toss to combine, making sure that all of the greens are coated. Top with the chickpeas, serve and enjoy!
