Preheat the air fryer to 400°F (200°C) for 5 minutes.

Unroll the crescent roll dough and separate it into triangles.

Spread 1 tablespoon of pesto on each triangle, leaving a small border around the edges.

Sprinkle 1 tablespoon of mozzarella cheese, 1 teaspoon of Parmesan cheese, garlic powder, and black pepper on top of the pesto.

Roll each triangle tightly from the wide end to the point, forming a spiral shape.

Place the rolled snails in a single layer in the air fryer basket, ensuring they are not touching.

Air fry at 400°F for 8-10 minutes, or until golden brown and puffed.

Remove and let cool for a few minutes before serving.
