Preheat oven to 180C/350F. Prepare a round 27cm x 3cm baking dish by rubbing with 1 tbsp butter and line with baking paper. Trim bread crusts and line the bottom of the baking dish and up the sides by cutting bread to fit baking dish to form a crust. Beat the eggs, milk, salt & pepper together and mix in remaining ingredients. Pour into the baking dish, brush remaining melted butter on the bread above the egg mixture and sprinkle remaining cheese evenly around the dish. Bake for 35 – 40 minutes or until the center is set. If the bread is browning too quickly, loosely cover with baking paper. Tip: This Frittata can be frozen, thawed and reheated. Cover with baking paper and foil, bake at 180C for about 35 minutes.
