In a toaster, cook bread slices until well toasted. In a blender, crumble bread slices in breadcrumbs. Microwave 30 ml of butter. In a bowl, mix melted butter with breadcrumbs. Pour the mixture in a large pie pan. With a fork, press well over breadcrumbs to form a crust.
Spray apples with lemon juice.
At medium heat, fry sliced leeks into 15 ml of butter. Salt and pepper. Cook at low heat for 10 minutes while stirring occasionally. Add flour and mix well. Pour into the pie pan. Into 5 ml of butter, caramelize diced apples. Pour over leeks. Season.
Whisk eggs with milk and half the cheese. Pour over apples and leeks mixture. Sprinkle with remaining cheese. Cook 30 minutes or until the crust is well browned.
