Creating turkey turnovers at home is easy if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Cook the Filling: In a skillet over medium heat, add olive oil. Sauté the diced onion and minced garlic until soft.
3. Add Vegetables: Incorporate the mixed vegetables and cook for another 2-3 minutes. Season with thyme, rosemary, salt, and pepper.
4. Combine Turkey and Cheese: Add the cooked turkey to the skillet. Stir in the shredded cheddar cheese until it’s all combined. Remove from heat and let the mixture cool slightly.
5. Prepare Puff Pastry: Roll out the puff pastry sheets on a lightly floured surface. Cut each sheet into circles (about 5-6 inches in diameter).
6. Fill Pastry: Place a spoonful of the turkey filling in the center of each circle, making sure not to overfill.
7. Seal the Turnovers: Fold each circle in half to create a half-moon shape. Press the edges together firmly and crimp with a fork to seal.
8. Egg Wash: Brush the top of each turnover with the beaten egg for a golden finish.
9. Bake: Place turnovers on the prepared baking sheet and bake in the preheated oven for 25-30 minutes or until golden brown.
10. Cool: Remove from the oven and let cool on a wire rack for about 10-15 minutes before serving.

This step-by-step guide will help ensure your turkey turnovers are nothing short of incredible!
