Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Rinse and thoroughly dry the chickpeas with a clean kitchen towel to ensure they become crisp during roasting.
On the prepared baking sheet, combine the chickpeas, broccoli florets, and chopped red bell pepper.
Drizzle with olive oil and sprinkle with sea salt, black pepper, and garlic powder, tossing until everything is evenly coated.
Roast for 20-25 minutes, tossing halfway through, until the vegetables are tender and the chickpeas are slightly golden and crisp.
While the vegetables roast, prepare the quinoa according to package instructions if not already cooked.
In a small mixing bowl, whisk together the non-fat Greek yogurt, lemon juice, and minced garlic until the dressing is smooth and creamy.
To assemble, spread the lemon-yogurt dressing at the bottom of a wide bowl and layer the cooked quinoa on top.
Add the roasted vegetable and chickpea mixture over the quinoa.
Finish the bowl by sprinkling the hemp hearts over the top for a boost of plant-based protein and a nutty texture.
