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 dry with a clean kitchen towel to ensure they get crispy.
Place the chickpeas, broccoli florets, and chopped red bell pepper on the baking sheet.
Drizzle with olive oil and sprinkle with garlic powder, sea salt, and black pepper, tossing well to coat evenly.
Roast the vegetables for 20-25 minutes, tossing halfway through, until the broccoli is tender and the chickpeas are golden.
While the vegetables roast, prepare the dressing by whisking together the Greek yogurt, lemon juice, tahini, and nutritional yeast in a small bowl until smooth.
Steam the shelled edamame for 3-5 minutes until bright green and tender.
Assemble the bowl by placing the cooked quinoa at the base, then topping with the roasted vegetables and steamed edamame.
Drizzle the creamy lemon-tahini yogurt sauce over the top and garnish with hemp hearts for extra texture.
