Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Drain and rinse the chickpeas, then pat them completely dry with a clean kitchen towel to ensure they get crispy.
Place the chickpeas and broccoli florets on the baking sheet, drizzle with olive oil, and toss with garlic powder, cumin, sea salt, and black pepper.
Roast the vegetables for 20-25 minutes, tossing halfway through, until the broccoli is tender with charred edges and the chickpeas are golden.
While the vegetables roast, prepare the high-protein dressing by whisking together the Greek yogurt, nutritional yeast, and lemon juice in a small bowl until smooth.
Assemble the bowl by placing the warm cooked quinoa at the base and topping it with the roasted broccoli and chickpeas.
Drizzle the yogurt sauce generously over the bowl and finish with a sprinkle of hemp seeds for added texture and nutrients.
