Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Rinse the chickpeas thoroughly and pat them very dry with a clean kitchen towel to ensure they get crispy.
In a large bowl, combine the chickpeas, broccoli florets, and chopped red bell pepper.
Drizzle with olive oil and season with sea salt, black pepper, and dried oregano, tossing until everything is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 to 25 minutes, or until the vegetables are tender and the chickpeas are slightly golden.
While the vegetables roast, prepare the protein-rich sauce by whisking together the non-fat Greek yogurt, lemon juice, and garlic powder in a small bowl until smooth.
Assemble the bowl by placing the warm cooked quinoa at the base, topping it with the roasted vegetable and chickpea mixture.
Finish by drizzling the creamy lemon-yogurt sauce over the top before serving.
