Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu for 15 minutes to remove excess moisture, then cut into half-inch cubes.
In a large mixing bowl, toss the tofu cubes and rinsed chickpeas with avocado oil, smoked paprika, garlic 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 minutes, flipping halfway through, until the tofu is golden and the chickpeas are slightly crispy.
While the protein roasts, steam the broccoli florets in a steamer basket over boiling water for 5 minutes or until they reach a vibrant green, tender-crisp texture.
In a small bowl, whisk together the tahini, lemon juice, and nutritional yeast, adding a tablespoon of warm water at a time until the sauce reaches a smooth, drizzling consistency.
Assemble the Buddha bowl by placing the cooked brown lentils at the base and topping them with the steamed broccoli, roasted tofu, and crispy chickpeas.
Finish the bowl by drizzling the creamy lemon-tahini sauce over the top and garnishing with hemp seeds for a final boost of plant-based protein.
