Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the firm tofu between paper towels to remove excess moisture, then cut into half-inch cubes.
Drain and rinse the chickpeas, then pat them dry thoroughly to ensure they get crispy in the oven.
Place the tofu cubes, chickpeas, and broccoli florets on the baking sheet; drizzle with olive oil and sprinkle with garlic powder, sea salt, and black pepper.
Toss the ingredients to coat evenly and spread them out in a single layer.
Roast for 20 to 25 minutes, tossing halfway through, until the tofu is golden and the broccoli edges are slightly charred.
While the vegetables roast, place the kale in a large serving bowl and drizzle with lemon juice, massaging the leaves with your hands for 1 minute until they soften and turn dark green.
Add the roasted tofu, chickpeas, and broccoli to the bowl with the kale.
Sprinkle the hemp hearts and nutritional yeast over the top, tossing gently to combine before serving.
