Preheat oven to 400°F and line a baking sheet with parchment paper.
Press the tofu to remove excess moisture, then cut into 0.5-inch cubes.
In a bowl, toss the tofu and chickpeas with olive oil, garlic powder, onion powder, salt, and pepper.
Spread the tofu and chickpeas onto the baking sheet and roast for 20 minutes until the tofu is golden and the chickpeas are slightly crisp.
While roasting, steam the broccoli florets until tender-crisp and massage the kale with a splash of lemon juice to soften.
Whisk together the nutritional yeast, tahini, and remaining lemon juice with a splash of water to create a smooth, creamy sauce.
Assemble the bowl by layering the kale, broccoli, roasted tofu, and chickpeas, then finish with a generous drizzle of the savory sauce.
