Creating delicious Vegetable Irish Pasties can be straightforward. Follow these easy steps:

1. Prepare the Pastry: In a large bowl, combine the all-purpose flour and salt. Add the chilled butter and rub in with your fingertips until the mixture resembles coarse crumbs.
2. Add Water: Gradually add cold water, one tablespoon at a time, mixing until a dough forms. Knead gently until smooth and wrap in plastic wrap. Chill in the refrigerator for at least 30 minutes.
3. Cook the Filling: In a skillet, heat olive oil over medium heat. Add the chopped onion and garlic, sautéing until soft and translucent.
4. Add Vegetables: Stir in the diced carrot and potato, cooking for about 5 minutes. Add peas, thyme, and rosemary, then season with salt and pepper. Cook for an additional 5 minutes until the vegetables are tender. Remove from heat and let cool.
5. Roll Out the Pastry: Preheat your oven to 400°F (200°C). On a floured surface, roll out the chilled pastry to about 1/8 inch thick. Cut out circles about 5-6 inches in diameter.
6. Fill the Pastry: Place a generous spoonful of the vegetable mixture in the center of each pastry circle. Fold the circle in half and press the edges together to seal. Use a fork to crimp the edges for a decorative touch.
7. Prepare for Baking: Place the pasties on a baking sheet lined with parchment paper. If desired, brush the tops with beaten egg for a golden color.
8. Bake: Bake in the preheated oven for 25-30 minutes or until the pastry is golden brown.
9. Cool: Remove from the oven and let cool for 5-10 minutes before serving.

This step-by-step process will lead you to scrumptious Vegetable Irish Pasties, making your cooking experience enjoyable and rewarding.
