Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a large mixing bowl, combine the chickpeas, broccoli florets, and diced red bell pepper.
Drizzle the olive oil over the vegetables and chickpeas, then sprinkle with garlic powder, sea salt, and black pepper.
Toss everything thoroughly to ensure an even coating of oil and spices, then spread in a single layer on the prepared baking sheet.
Roast for 20 to 25 minutes, tossing halfway through, until the vegetables are tender and the chickpeas are slightly crisp.
Remove the tray from the oven and immediately sprinkle the nutritional yeast over the hot vegetables, tossing to create a savory crust.
In a small bowl, whisk the non-fat plain Greek yogurt with the lemon juice until smooth and creamy.
Spread the yogurt mixture across the bottom of a shallow serving bowl to create a protein-rich base.
Pile the roasted vegetable and chickpea mixture on top of the yogurt.
Finish the bowl by sprinkling the hemp hearts over the top for added texture and a boost of plant-based protein.
