O.k. this is a recipie that I got from a cook book that my grandmother gave me.
Here goes:
4 cups sliced apples(or you can use 2 cans of apple pie filling)\
1/2c flour
3/4 tsb cinnamon
2/4cup brown sugar
1/2 cup oatmeal
1/2 cup soft butter or oleo
K use butter to grease pan 8x8 or 9x9 in, not the 1/2 cup spread out your apples on the bottom of the pan. Next mix your ingrediants till they are crumbly, spread over the apples and top with nuts if you want to. Back at midrange temps till the apples are done. Forewarning here, the crumb topping may turn out very sweet, so if you don't like it sweet you might want to find a different recipie. I personally like it though
