1 package INSTANT Vanilla Pudding mix  (four serving size)
1 large package of cream cheese at room temperature
1 1/4 cups of milk
1 prepared 9" graham cracker pie shell
1 can of cherry or blueberry pie filling

With an electric beater cream the cheese with the milk.  Gradually beat in the pudding mix.  Beat on high till the mixture is very smooth and fluffy.
Pour into the crust and refrigerate overnight.  Before serving, top with the pie filling.

This is a very quick and easy dessert.  To spice it up, replace 1/3 of a cup of the milk with Baily's Irish Cream Liquer. 

At Christmas I used egg nog instead of the milk.  It was great.
