Preheat oven to 400°F and line a large baking tray with parchment paper.
Press the extra firm tofu for 15 minutes to remove moisture, then cut into 1/2-inch cubes.
Peel and dice the sweet potato into small 1/2-inch cubes for even roasting.
In a mixing bowl, combine tofu, sweet potato, chickpeas, and broccoli with avocado oil, sea salt, pepper, garlic powder, and smoked paprika.
Spread the seasoned mixture onto the prepared tray and roast for 25 minutes until the edges are golden and crisp.
Place the kale in a separate bowl with half of the lemon juice and massage with your hands until the leaves are tender.
In a small jar, whisk the tahini, nutritional yeast, and remaining lemon juice with a splash of warm water until smooth.
Divide the massaged kale into bowls and top with the warm roasted tofu and vegetable medley.
Finish by sprinkling hemp seeds over the top and drizzling with the prepared zesty tahini sauce.
