Preheat oven to 180°C (325F). Lightly grease a 3cm(1 1/2") deep, 22cm (8") (base) flan or quiche dish. Using a rolling pin, roll out bread until flat. Arrange bread over base and sides of dish, overlapping so base is completely covered. Place dish on an oven tray. Bake for 10 minutes or until bread is lightly toasted.

Heat a non-stick frying pan over medium heat. Add bacon and cook, stirring, for 5 minutes. Add onion. Cook, stirring, for a further 5 minutes or until onion is soft.

Spread half the bacon mixture over bread base. Pour eggwhites over bacon mixture. Crack whole eggs over mixture. Sprinkle with remaining bacon mixture and combined mozzarella and tasty cheeses. Season with salt and pepper.

Bake pie for 20 minutes or until eggs have set. Cut into 4. Serve with mixed steamed vegetables.
