Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Press the firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a mixing bowl, toss the tofu cubes with nutritional yeast, garlic powder, sea salt, and black pepper until evenly coated.
Spread the coated tofu, chickpeas, and broccoli florets onto the prepared baking sheet. Drizzle with olive oil and toss gently.
Roast for 25-30 minutes, flipping the tofu halfway through, until the tofu is golden and the broccoli is slightly charred.
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 softened.
In a small jar, whisk together the tahini, remaining lemon juice, and 1 tablespoon of warm water until smooth and creamy.
Assemble the bowl by placing the massaged kale at the bottom and topping it with the roasted tofu, chickpeas, and broccoli.
Finish by drizzling the lemon-tahini dressing over the top and serve immediately.
