Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they crisp up during roasting.
In a large mixing bowl, combine the chickpeas, broccoli florets, and chopped red bell pepper.
Drizzle the vegetables with olive oil and season with sea salt, black pepper, and garlic powder, tossing well to coat evenly.
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-crisp and the chickpeas are slightly golden.
While the vegetables roast, prepare the dressing by whisking together the non-fat Greek yogurt, lemon juice, and dried oregano in a small bowl.
Once roasted, transfer the vegetable and chickpea mixture to a serving bowl.
Drizzle the creamy lemon-yogurt dressing over the top and finish with a sprinkle of hemp seeds for added protein and texture.
