Add the sweet potatoes to a baking sheet. Sprinkle with the garlic powder, paprika, salt, and pepper, and drizzle with olive oil. Toss until the sweet potato is well-coated in the spices, then spread out evenly. Bake for 15 minutes, or until tender.
In a small bowl, add the pumpkin seeds, chili powder, 1 tablespoon maple syrup, and salt, and mix until well-combined. Spread the pumpkin seeds out on a baking sheet so they’re not touching each other.
Add to the oven with the sweet potato and bake for 10 minutes, stirring halfway through, until toasted.
In a liquid measuring cup, combine the tahini, remaining tablespoon of maple syrup, lemon juice, salt, and pepper. Mix well, then add 1 tablespoon of water at a time until desired consistency is reached.
In a large bowl, drizzle the kale with olive oil. Massage with your hands until the kale is tender and has reduced in volume by about a third.
Add the quinoa, roasted sweet potatoes, red onion, and pumpkin seeds. Drizzle with tahini dressing and toss well.
