In a medium skillet, heat oil. Cook onions and apples until slightly softened over medium heat, about 4 minutes. Stir in raisins and cook another 30 seconds. Let mixture cool slightly.

In a large bowl beat eggs with sugar, cinnamon, salt and pepper. Stir in apple mixture and noodles until well combined. Pour into baking pan. Bake about 1 hour or until golden brown on top. Serve warm or room temperature cut into squares.
