Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Press the tofu to remove excess water, then cut it into 1-inch cubes.
In a bowl, whisk together the low sodium soy sauce, garlic powder, black pepper, and a pinch of salt.
Gently toss the tofu cubes in the mixture, then sprinkle with cornstarch to coat evenly.
Place the tofu on the prepared baking sheet and drizzle with 1 tsp of olive oil.
On a separate baking sheet, spread out broccoli florets (if not pre-cut, chop broccoli into bite-sized pieces). Drizzle with the remaining olive oil, and season lightly with salt and pepper.
Bake the tofu and broccoli in the oven for 20-25 minutes, flipping the tofu halfway through, until the tofu is golden and crispy and the broccoli is tender and slightly charred.
While the tofu and broccoli are baking, prepare the quinoa according to package directions (if not already cooked).
To serve, layer the quinoa on a plate, top with the crispy tofu and roasted broccoli, and enjoy your nutrient-packed meal.
