01 - Preheat the oven to 350°F. Grease and line an 8x4-inch loaf pan with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, and black pepper.
03 - In a separate bowl, beat the eggs, then whisk in the milk and olive oil until smooth.
04 - Fold the wet ingredients into the dry mixture just until combined, taking care to avoid overmixing.
05 - Gently stir in cheese, olives, sun-dried tomatoes, parsley, chives, and garlic until evenly distributed throughout the batter.
06 - Pour the batter into the prepared loaf pan and smooth the surface evenly.
07 - Bake for 40 to 45 minutes until a toothpick inserted into the center comes out clean and the crust is golden brown.
08 - Allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
