Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced bell peppers, and chickpeas onto the baking sheet, then drizzle with olive oil and sprinkle with garlic powder, salt, and pepper.
Toss the vegetables and chickpeas until evenly coated, then roast in the oven for 20 minutes until the edges are golden and tender.
While the vegetables roast, bring a small pot of water to a boil, carefully lower in the egg, and simmer for 6.5 minutes for a jammy yolk.
Remove the egg and place it in an ice bath immediately, then peel and slice it in half once cooled.
In a small mixing bowl, stir together the nonfat Greek yogurt and lemon juice until the consistency is smooth and pourable.
Assemble the bowl by placing the cooked quinoa at the base, followed by the roasted vegetable and chickpea mixture.
Finish the bowl by adding the halved egg, sprinkling the hemp seeds over the top, and drizzling with the lemon-yogurt sauce.
