Drain the extra-firm tofu to remove excess moisture, then wrap it in a clean kitchen towel and press it for about 15 minutes.

Cut the tofu into bite-sized cubes.

In a bowl, toss the tofu cubes with buffalo sauce and melted vegan butter until thoroughly coated.

Preheat the air fryer to 400°F (200°C). Arrange the tofu in a single layer in the air fryer basket and cook for about 12 minutes, shaking halfway through.

In a large bowl, add chopped kale, drizzle with Caesar dressing, and toss well to coat.

Once the tofu is air-fried, carefully place it on top of the dressed kale and add croutons if desired.
