Preheat oven to 375 degrees
Peel the apples, then cut and slice them into narrow pieces. Place them in the baking dish of your choosing.
Mix flour, sugar, cinnamon, salt and butter togetherNote: I used 1/2 cup of white sugar and 1/2 cup of brown :)
Sprinkle the mixture evenly over the apples.
Let it bake for 40 minutes or until golden brown.
Slice, eat and enjoy!
