Filling and Baking the Shells

Spread a small amount of sauce in the bottom of the baking dish
Fill each shell with approximately 1.5 tablespoon pumpkin cheese filling and place in the dish open side up
Once all shells are filled pour the sauce over the top of all the shells. Use a spoon to spread sauce out trying to cover the tops of all the shells
Bake for 30 minutes until shells are bubbly. Serve hot and enjoy!
Notes
Shells can be boiled and kept in the fridge up to 24 hours ahead of time in an airtight container.Cook the shells slightly less done than al dente. They will continue cooking in the oven when warming the filling. As soon as the filling in the center of a centrally located shell is hot, it is ready to go. You can check the temperature with a digital meat thermometer, when it reads 170°F, they are hot enough.
