Preheat the oven to 400°F. Rinse and drain the chickpeas, then pat them dry. Toss with a pinch of salt, pepper, and a few drops of oil. Spread on a baking sheet and roast for 25-30 minutes until crispy.
Peel and cube the sweet potato into small, even pieces. Toss lightly in oil, salt, and pepper. Roast alongside the chickpeas for about 25-30 minutes until tender and slightly caramelized.
While the chickpeas and sweet potato roast, press the tofu gently to remove excess moisture, then cut into cubes. Sauté the tofu in a non-stick pan over medium heat with a sprinkle of salt until golden on all sides, about 6-8 minutes.
Prepare the lemon-tahini dressing by whisking together 0.5 tablespoon tahini, 1 tablespoon lemon juice, a splash of water, and a pinch of salt until smooth.
In a bowl, layer the chopped kale, then add the roasted chickpeas, sweet potato, and sautéed tofu.
Sprinkle 1 tablespoon hemp seeds and 2 tablespoons nutritional yeast over the bowl.
Drizzle the lemon-tahini dressing over the entire bowl, toss lightly, and serve immediately.
