Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium bowl, toss the tofu cubes and chickpeas with olive oil, garlic powder, onion powder, sea salt, and black pepper until evenly coated.
Spread the tofu and chickpeas in a single layer on the prepared baking sheet and roast for 25-30 minutes, tossing halfway through, until golden and crispy.
While the protein roasts, lightly steam the broccoli florets and chopped kale in a steamer basket for 4-5 minutes until tender and bright green.
Prepare the dressing by whisking together the tahini, lemon juice, and nutritional yeast in a small bowl, adding a tablespoon of warm water at a time until a creamy consistency is reached.
Assemble the Buddha bowl by placing the steamed greens at the base, topping with the roasted tofu and chickpeas, and finishing with a generous drizzle of the savory tahini sauce.
