Apple Crisp

My friend Kristi made this for us when we went to eat dinner with them one night. It was super good--probably my favorite apple crisp.

Filling:
6 apples, peeled and cut
1/2 cup sugar
1/4 tsp salt
1 tsp. cinnamon

Topping:
1 cup butter
1 cup brown sugar
1 cup flour
1 cup oatmeal

Preparation: Preheat oven to 350 degrees. Mix the all the ingredients for the topping together, using your hands. Set aside. Mix the filling together in a bowl and place in the bottom of a 9x7 pan. Sprinkle the topping on the top of the apple mixture and cook for 25 min.
