Apple Betty

This is a recipe of my Grandma Doubt's. It is delicious and very easy to make. Also, I thought with Fall coming on, it makes me think of apple picking.

12 to 15 apples, peeled and sliced
Put into 9 x 13 baking dish.
Take 9 slices of white bread. Sprinkle each slice with water and tear into large chunks. Lay on top of apples.
Sprinkle over top with 1 cup sugar and a small amount of salt.( probably about 1/2 tsp. salt )
Then sprinkle generously with cinnamon
Pour in 1 1/2 cups water
Slice 1/2 stick margarine over top. Cover with foil. Bake at 350 degrees for 1 hour. Remove foil last 10 minutes.
