Bake and let cool - then split in 1/2. Scoop out the centers and add:
2 T butter
1/2 c whipping cream
1/2 t salt
1/4 t white pepper
1/2 c Parmesan cheese
Mix that together and then restuff the shells. Bake 15 minutes at 350. I sprinkle the tops with scallions and/or paprika.
We eat these for all major holidays. They're NOT diet food!
