Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the cooked chickpeas completely dry with a paper towel to ensure they crisp up beautifully in the oven.
Place the chickpeas, broccoli florets, and chopped red bell pepper on the baking sheet and toss with olive oil, sea salt, black pepper, and garlic powder.
Roast the vegetables and chickpeas for 20-25 minutes, tossing halfway through, until the broccoli is tender and the chickpeas are golden.
While the vegetables roast, combine the non-fat Greek yogurt, lemon juice, and dried oregano in a small bowl, whisking until the consistency is smooth.
Place the warm cooked quinoa in the base of a serving bowl.
Spread the lemon-yogurt mixture over the quinoa or place a generous dollop in the center.
Top the bowl with the roasted vegetable and chickpea mixture and finish with a sprinkle of hemp hearts for a nutty crunch and extra protein.
