Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the firm tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
In a large mixing bowl, toss the tofu cubes, chickpeas, and broccoli florets with olive oil, garlic powder, sea salt, and black pepper until evenly coated.
Spread the tofu and vegetable mixture onto the prepared baking sheet in a single layer and roast for 20 minutes until the tofu is golden and the broccoli is tender.
While the vegetables roast, whisk together the tahini, lemon juice, and nutritional yeast in a small bowl, adding a splash of warm water to reach a smooth, pourable consistency.
Place the kale in a serving bowl and massage it with a tiny pinch of salt for 30 seconds until it becomes soft and dark green.
Top the massaged kale with the roasted tofu, chickpeas, and broccoli, then drizzle the creamy tahini dressing over the entire bowl before serving.
