Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Press the tofu between paper towels for 10 minutes to remove excess moisture, then slice into 1-inch cubes.
In a large mixing bowl, combine the tofu cubes, chickpeas, broccoli florets, and sliced red bell pepper.
Drizzle the mixture with olive oil and sprinkle with sea salt, black pepper, and garlic powder, tossing until everything is evenly coated.
Spread the ingredients in a single layer on the prepared baking sheet and roast for 25 minutes until the tofu is golden and the vegetables are tender.
While the vegetables roast, simmer the quinoa in 0.25 cup of water for 12 minutes, then let it stand covered for 5 minutes before fluffing with a fork.
In a small bowl, whisk together the apple cider vinegar, tamari, toasted sesame oil, maple syrup, and nutritional yeast to create the dressing.
Divide the cooked quinoa into serving bowls, top with the roasted tofu and vegetable mixture, and drizzle the tangy dressing over the top.
