Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Drain the tofu and press it between paper towels for 10 minutes to remove excess moisture, then cut into 1/2-inch cubes.
Place the tofu cubes, chickpeas, and broccoli florets on the prepared baking sheet and drizzle with the olive oil.
Sprinkle the garlic powder, smoked paprika, sea salt, and black pepper over the vegetables and protein, tossing well to ensure an even coating.
Roast in the oven for 20 to 25 minutes, flipping halfway through, until the tofu is golden and the chickpeas are slightly crispy.
While the vegetables roast, whisk together the tahini, lemon juice, nutritional yeast, and water in a small bowl until a smooth, pourable dressing forms.
Place the fresh baby spinach in a large serving bowl, top with the warm roasted mixture, and finish with a generous drizzle of the creamy tahini dressing.
