Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain the firm tofu and press it between paper towels for 5 minutes to remove excess moisture, then cut into 1/2-inch cubes.
Rinse and drain the chickpeas, patting them very dry with a clean kitchen towel to ensure they get crispy in the oven.
In a large mixing bowl, combine the tofu cubes, chickpeas, and broccoli florets.
Drizzle with olive oil and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper; toss until everything is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 minutes, tossing halfway through, until the tofu is golden and the broccoli is tender.
While the vegetables roast, whisk together the nonfat Greek yogurt and lemon juice in a small bowl until smooth to create the dressing.
Place the warm cooked quinoa in the base of a serving bowl.
Top the quinoa with the roasted tofu, chickpeas, and broccoli.
Drizzle the lemon-yogurt sauce over the top and garnish with pumpkin seeds for an extra boost of protein and texture.
