Lillian's Skillet Apples

My mother used to make these all the time whenever we kids had not eaten the apples fast enough.  She liked to make this with pork chops and we love it. 
2 apples (I prefer Granny Smith), cored and sliced thin (I keep the peel on mine.)
3 T. butter
2 T.  brown sugar
1 tsp. cinnamon
1 tsp. nutmeg
a pinch of salt

Melt butter in a skillet--cast iron works best.  Add alll other ingredients and toss on medium heat until tender but not falling apart.  Delicious on top of pancakes or rolled in crepes, too.  I just like them as a side dish.
