Preheat your oven to 400°F (200°C).
Press the tofu for at least 15 minutes to remove excess moisture. Once pressed, cut the tofu into 1-inch cubes.
In a bowl, gently toss the tofu cubes with olive oil, cornstarch, salt, and pepper to evenly coat.
Chop the red bell pepper into strips, slice the zucchini into half-moons, and cut the red onion into wedges.
Place the chopped vegetables on a baking sheet, drizzle lightly with olive oil, and season with salt and pepper.
Arrange the tofu cubes on a separate baking tray or on one side of the same tray if space allows. Roast the tofu for 25 minutes, turning halfway to achieve even crispiness.
Simultaneously, roast the vegetables for approximately 20 minutes until they are tender and slightly caramelized.
While the tofu and vegetables are roasting, prepare the quinoa according to package instructions.
To serve, layer a base of quinoa in a bowl, top with roasted vegetables and crispy tofu, and finish with a generous sprinkle of hemp seeds.
Enjoy your balanced and flavorful meal!
