Preheat your oven to 400°F 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 crispness.
On the prepared baking sheet, toss the chickpeas, broccoli florets, and sliced red bell pepper with the olive oil, sea salt, black pepper, garlic powder, and smoked paprika.
Spread the vegetables and chickpeas in a single layer and roast for 20-25 minutes, tossing halfway through, until the broccoli is charred at the edges and the chickpeas are golden.
While the vegetables roast, whisk together the non-fat Greek yogurt and lemon juice in a small bowl until the mixture is smooth and creamy.
To assemble, spread the lemon-yogurt mixture across the bottom of a shallow bowl and top with the warm roasted vegetables and chickpeas.
Finish the bowl by sprinkling the hemp hearts over the top for a nutty crunch and a boost of plant-based protein.
