Whip together the sour cream and cream cheese. Spread evenly over the bottom of the pie shell. Pour the can of blueberry (or any favorite fruit filling)into the pie shell and spread evenly.
Make the meringue for a 9 inch pie shell, and spread that evenly over the top, creating swirls and peaks as desired.
Bake at 350 degrees until peaks and swirls are lightly browned (from 10-20 minutes-so watch!). Remove from oven, and cool away from drafts. When pie has cooled completely, store-covered-in the refrigerator.
