Puffed Pastry Sheet
Sliced Swiss Cheese
Thaw the puffed pastry sheet a little bit. Just enough that you can break it into the three sections that are already cut. Take one of the sections and spread sour cream on it. Layer ham and cheese on top of the sour cream. Place another section of the pastry on top. Repeat sour cream, ham, and cheese once more. Place the final section of puffed pastry on top. Spread sour cream. Bake according to package directions or until the pastry is puffy and golden.
