Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them completely dry with a clean kitchen towel to ensure they get crispy.
Place the broccoli florets, diced red bell pepper, and dried chickpeas onto the baking sheet.
Drizzle with olive oil and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika; toss well to coat every piece evenly.
Roast for 20-25 minutes, tossing halfway through, until the vegetables are tender and the chickpeas are slightly golden.
While the vegetables roast, prepare the protein-boosted dressing by whisking the Greek yogurt, nutritional yeast, and lemon juice in a small bowl until smooth.
Warm the pre-cooked quinoa in a small pan or microwave if necessary.
To assemble, place the warm quinoa in a bowl and top with the roasted vegetable and chickpea mixture.
Add a generous dollop of the savory yogurt sauce and finish by sprinkling the hemp hearts over the top for extra texture and protein.
