Preheat your oven to 375°F.

Prepare the crawfish filling by sautéing onions, bell peppers, and garlic in a skillet with a splash of olive oil until fragrant and translucent, about 5-7 minutes.

Combine the crawfish tails with the sautéed vegetables and season with Cajun spices, salt, and pepper. Cook for another 3-5 minutes until everything is well mixed and heated through.

Roll out the dough on a floured surface to about ¼ inch thick.

Spread the crawfish mixture evenly over half of the rolled-out dough, leaving some space at the edges for sealing later.

Fold the other half of the dough over the filling and pinch the edges to seal it tightly.

Bake in the preheated oven for 25-30 minutes or until golden brown and puffed up beautifully.

Cool for a few minutes before slicing into it.
