Directions
- Preheat your oven to 375°F (190°C).
- In a large skillet, heat olive oil and butter over medium heat. Add the onion, leeks, and garlic, and sauté for about 5 minutes until the vegetables are softened.

- Add the shredded chicken to the sauce and stir to combine. Remove from heat.
- Transfer the mixture into a baking dish and spread it out evenly.
- Roll out the puff pastry and place it over the chicken mixture. Trim the edges and pinch the seams to seal.
