Preheat oven to 375 degrees. In a bowl, combine brown sugar, butter, cinnamon, nutmeg, flour and salt. Whisk to combine. Slice each half of an apple into thin slices three quarters of the way down, leaving the bottom of the halved apple intact. (This method of slicing is called Hasselback.) Place apple halves flat side down in a baking dish. Spoon or brush half of the brown sugar/butter mixture over the apples. Cover and bake for 25 minutes or until apples are cooked but still slightly firm. Meanwhile, make chicken.
