Hey Linda!
I remember this recipe well and continue to make it even now...it's always been my favorite!

1 Redi Made graham cracker crust
1 can sweetened condensed milk
1/3 to 1/2 cup lemon juice or lime juice (amt. depending on how sweet or how tart you want it)
1 (8 oz.) pkg. cream cheese, softened
1 can cherry pie filling (for serving)

Mix together above ingredients and pour into graham crust. Refrigerate several hours or overnight.

Top with 1 can cherry or blueberry pie filling before serving.
