Step 1

Preheat oven to 180°C. Grease 6 holes of a 1/3-cup (80ml) muffin pan. Place 1 slice of bread on a clean work surface. Arrange another slice of bread on top at a 45-degree angle. Use a rolling pin to roll out bread slices until 5mm thick. Repeat with remaining bread slices. Line the prepared holes with bread, pressing down firmly. Spray with olive oil spray. Bake for 15 mins or until just golden.

Step 2

Combine zucchini, cheddar, bacon and chives in a bowl. Divide evenly among the bread cases. Whisk the egg and milk in a jug and pour evenly over the zucchini mixture. Season. Bake for 20-25 mins or until the egg mixture is light golden and just set. Cool slightly. Serve warm or at room temperature.
