Dollar tree apple pie with graham cracker crust and streusel topping

You can make a delicious apple pie with ingredients right from dollar tree! You will need 1 pre-made graham cracker pie crust, 1 can apple pie filling, quick oats, margarine, light brown sugar, all purpose flour, and cinnamon. First make the streusel topping. Combine 2/3 c all purpose flour and 6tbs slightly melted margarine in mixing bowl. Mix well. Add 1/2 c quick oats, 1/3 c light brown sugar, and 1/2 tsp cinnamon. Mix ingredients well. Next add the apple pie filling to graham cracker crust. Spoon streusel topping on top of apple pie filling. Spread out to cover pie. Bake at 375 for 35mins. Let cool about 1hr before serving. Serve warm, alone or with cool whip or vanilla ice cream. Enjoy!

Note: all ingredients are available at my dollar tree. I did not buy the flour or cinnamon there, I already had both at home, but they do sell both ingredients. They even sell the cool whip I used as well.
