Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them thoroughly dry with a paper towel to ensure maximum crispiness.
Place the chickpeas and broccoli florets on the baking sheet and toss with olive oil, sea salt, black pepper, and garlic powder until evenly coated.
Roast the vegetables for 20 to 25 minutes, tossing halfway through, until the broccoli is tender with charred edges and the chickpeas are slightly golden.
While the vegetables roast, whisk together the non-fat Greek yogurt, lemon juice, and dried oregano in a small bowl until the dressing is smooth and creamy.
Assemble the bowl by placing the fresh spinach and cooked quinoa at the bottom as a base.
Top the greens and grains with the warm roasted broccoli and chickpeas.
Sprinkle the crumbled feta cheese and hemp seeds over the top, then drizzle generously with the lemon-herb dressing before serving.
