1-First Step: Preheat oven and prepare pan Preheat your oven to 180°C (350°F) or 160°C fan (325°F). Lightly oil a 23 x 33 cm (9 x 13 inch) metal pan and line the base and long sides with baking paper to prevent sticking and help lift the bread out easily.

2-Second Step: Mix dry ingredients In a large bowl, whisk together 2 cups plain flour, 1 ½ teaspoons baking powder, ½ teaspoon sifted baking soda, and ½ teaspoon salt. This ensures even distribution of leavening agents for a consistent rise.

3-Third Step: Mix wet ingredients In a separate bowl, whisk 1 egg, 1 cup milk, ¼ cup sour cream (or plain yogurt), and 3 tablespoons olive oil until well combined and smooth.

4-Fourth Step: Combine wet and dry mixtures Pour the wet ingredients into the dry ingredients. Gently fold with a rubber spatula until mostly combined, leaving some small lumps for tenderness. Avoid overmixing to maintain a soft crumb.

5-Fifth Step: Add cheese to batter Fold in 1 cup shredded cheese into the batter until evenly distributed, infusing the bread with a cheesy flavor throughout.

6-Sixth Step: Spread batter and add toppings Spread the thin batter evenly into the prepared pan it will rise during baking. Spread ½ cup pizza sauce evenly over the batter. Sprinkle 1 ½ cups shredded cheese on top, then distribute sliced red onion, green capsicum, kalamata olives, and pepperoni slices evenly.

7-Seventh Step: Bake uncovered Bake uncovered for 25 minutes until the edges start to turn golden and cheese bubbles.

8-Eighth Step: Cover and continue baking Cover the pan loosely with foil or a baking tray to prevent the cheese from over-browning. Bake for an additional 15 minutes until the bread is cooked through.

9-Final Step: Cool and slice Allow the lunchbox pizza bread to cool in the pan for 10 minutes. Then lift or slide it onto a wire rack and cool another 10 minutes before slicing into 12 portions. This resting prevents a doughy texture and helps slices hold shape.
