Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
In a large bowl, toss the tofu cubes, chickpeas, and broccoli florets with the olive oil, garlic powder, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 minutes, flipping halfway through, until the tofu is golden and crispy.
While the vegetables roast, place the chopped kale in a bowl with half of the lemon juice and massage with your hands for 1-2 minutes until tender.
In a small jar or bowl, whisk together the nutritional yeast, the remaining lemon juice, water, and Dijon mustard to create a smooth dressing.
Assemble the bowl by placing the massaged kale at the base, topping with the roasted tofu, chickpeas, and broccoli, and drizzling the savory dressing over the top.
