Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Press the extra firm tofu between paper towels to remove excess moisture, then cut into uniform 1/2-inch cubes.
In a large mixing bowl, toss the tofu cubes, chickpeas, and broccoli florets with the olive oil, sea salt, black pepper, and garlic powder until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 minutes, tossing halfway through, until the tofu is golden and the broccoli edges are crispy.
While the vegetables roast, place the chopped kale in a serving bowl and drizzle with lemon juice, massaging the leaves with your hands for 1 minute to soften the texture.
Remove the roasted components from the oven and pile them onto the bed of massaged kale.
Garnish the bowl with nutritional yeast and hemp seeds for a savory, protein-rich finish.
