Preheat the oven to 425°F. Line a baking sheet with parchment paper.

Set the pressed tofu on a cutting board and slice into 1-inch cubes. Transfer the tofu cubes to a large bowl.

In a small bowl, whisk together the sriracha sauce, olive oil, salt, and black pepper.

Pour the sriracha mixture over the tofu and gently toss to coat.

Arrange the tofu pieces in a single layer so they do not touch the lined baking sheet. Bake for 35 minutes, or until tofu is lightly crisp in places.

Adjust seasoning to taste, sprinkle with scallions, and serve hot.
