Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Rinse the chickpeas and pat them very dry with a clean kitchen towel to ensure they get crispy in the oven.
Slice the zucchini into half-moons and dice the red bell pepper into bite-sized pieces.
In a large bowl, toss the chickpeas, zucchini, and bell pepper with olive oil, smoked paprika, garlic powder, sea salt, and black pepper until evenly coated.
Spread the vegetable and chickpea mixture in a single layer on the prepared baking sheet and roast for 20-25 minutes, tossing halfway through.
While the vegetables roast, prepare the high-protein sauce by whisking together the Greek yogurt, nutritional yeast, and lemon juice in a small bowl until smooth.
Assemble the bowl by portioning the roasted vegetables and chickpeas into a serving dish, topping with a generous dollop of the lemon-yogurt sauce, and finishing with a sprinkle of hemp seeds.
