Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Press the extra-firm tofu between paper towels for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a large bowl, toss the tofu cubes, chickpeas, and broccoli florets with the tamari, garlic powder, sea salt, black pepper, and 2 tablespoons of the nutritional yeast.
Spread the seasoned mixture in a single layer on the prepared baking sheet and roast for 20-25 minutes, flipping halfway through, until the tofu is golden and the broccoli is tender.
While the vegetables roast, place the chopped kale in a bowl with a splash of lemon juice and massage with your hands for 1-2 minutes until the leaves are softened and dark green.
Prepare the dressing by whisking together the tahini, the remaining 1 tablespoon of nutritional yeast, the remaining lemon juice, and water until smooth and velvety.
Assemble the bowl by layering the massaged kale at the bottom and topping it with the roasted tofu, chickpeas, and broccoli.
Drizzle the zesty tahini dressing over the entire bowl and serve immediately.
