Make a crumble mixture of dry ingredients by cutting in butter. Set mixture aside. Put the pie filling in a 9 x 13 pan and then top with  mixture. Sprinkle with cinnamon. Bake at 350 degrees for 35 minutes. Can be served warm or cold.

A favorite variation of this recipe:
I use one can of apricot pie filling and 1 can of pears or apple pie slices. The apricots add a nice tartness to the recipe.
