Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Press and drain the tofu to remove excess moisture, then cut it into 1-inch cubes.
In a bowl, gently toss the tofu cubes with cornstarch, garlic powder, salt, and pepper until evenly coated.
Spread the tofu on the baking sheet and bake for about 25-30 minutes, flipping halfway through, until tofu is crispy and golden.
Meanwhile, peel and cube the sweet potato into bite-sized pieces. Toss with a bit of olive oil, salt, and pepper, then spread on a separate baking sheet. Roast in the oven for 20-25 minutes until tender and slightly caramelized.
Prepare the quinoa as per package instructions if not already cooked.
Lightly steam or microwave the shelled edamame until heated through.
In a bowl, combine the cooked quinoa, roasted sweet potato, and edamame. Drizzle with the remaining olive oil and gently toss to mix.
Top the bowl with the crispy baked tofu and serve warm.
