Preheat oven to 400°F and line a large baking sheet with parchment paper.
Press the tofu to remove excess moisture, then cut into 1/2-inch cubes.
In a large bowl, toss the tofu cubes, chickpeas, and broccoli florets with olive oil, garlic powder, onion powder, sea salt, and black pepper.
Spread the mixture in a single layer on the baking sheet and roast for 20-25 minutes until the tofu is golden and chickpeas are slightly crispy.
While roasting, place the chopped kale in a bowl and massage it with lemon juice for 1 minute until softened.
Assemble the bowl by layering the massaged kale at the bottom and topping with the roasted tofu, chickpeas, and broccoli.
Whisk the tahini with a splash of warm water to reach a pourable consistency and drizzle it over the bowl.
Garnish with nutritional yeast and hemp hearts before serving.
