Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Cut the seitan and sweet potato into bite-sized cubes and place them on the baking sheet.
Drizzle the seitan and sweet potato with olive oil and season with garlic powder, smoked paprika, sea salt, and black pepper.
Toss well to coat and roast for 20-25 minutes, flipping halfway through, until the sweet potatoes are tender and the seitan is slightly crispy.
While the vegetables roast, place the chopped kale in a small bowl with the lemon juice and a pinch of salt, massaging the leaves with your hands for 1-2 minutes until they become dark green and tender.
In a serving bowl, layer the cooked quinoa and rinsed chickpeas as the base.
Top the grains with the roasted sweet potato, crispy seitan, and massaged kale.
Garnish the bowl with hemp seeds for an extra boost of protein and healthy fats before serving.
