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 maximum crispiness.
In a large mixing bowl, combine the chickpeas, broccoli florets, and chopped red bell pepper.
Drizzle with olive oil and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper, tossing until everything is evenly coated.
Spread the vegetables in a single layer on the prepared baking sheet and roast for 20-25 minutes, tossing halfway through, until the chickpeas are golden and the broccoli edges are slightly charred.
While the vegetables roast, whisk together the Greek yogurt, tahini, and lemon juice in a small bowl until the sauce is smooth and creamy.
To assemble, spread the lemon-tahini yogurt across the bottom of a shallow bowl.
Pile the roasted chickpeas and vegetables on top of the yogurt base.
Finish the bowl by sprinkling evenly with nutritional yeast and hemp hearts for an extra boost of protein and flavor.
