Instructions:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
2. Prepare the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, salt, and black pepper.
3. Incorporate the Butter: Using a pastry cutter or your fingers, cut in the chilled and diced butter until the mixture resembles coarse crumbs.
4. Add Cheese and Vegetables: Stir in the grated sharp cheddar cheese, diced sun-dried tomatoes, and chopped green onions.
5. Prepare the Wet Ingredients: In a separate bowl, whisk together the buttermilk and beaten egg.
6. Combine Wet and Dry Ingredients: Make a well in the center of the dry ingredients and pour in the buttermilk mixture. Stir just until a dough forms.
7. Knead and Shape: Turn the dough out onto a lightly floured surface and knead briefly. Divide the dough in half and form each half into a round, about 1 inch thick.
8. Cut and Arrange: Cut each round into 6 wedges and place them on the prepared baking sheet.
9. Brush with Beaten Egg: Brush the tops of the scones with the beaten egg.
10. Bake: Bake for 18 to 20 minutes, or until the scones are golden brown and a toothpick inserted into the center of a scone comes out clean.
11. Serve and Enjoy: Serve the scones warm, with butter and jam, or as a delightful side for soups, braais, or roast meats and vegetables.

Enjoy these Savoury Scones as a flavorful addition to any meal or as a delightful snack on their own.
