Parboil the jumbo shells
While the shells are boiling create the alfredo sauce by melting the butter in a pan.
Add the garlic and Greek seasoning blend and salt and pepper to the melted butter
Add milk and half the parmesan cheese whisk until the cheese is melted
Simmer until it thickens slightly
Add the heavy cream and the remainder of the cheese and simmer.
Continue to simmer for 3 minutes then remove the alfredo sauce from the heat
Create your jumbo shell filling by combining the ricotta cheese, shredded chicken, the minced garlic, Italian cheese, chopped spinach oregano, basil, salt and pepper
Drain the shells and fill them with the filling
Place ½ c of alfredo sauce in the bottom of a glass pan
Line the pan with the filled shells and top with the alfredo sauce and the remaining ¼ c of Parmesean cheese
Bake at 400 for 20 minutes
Enjoy!
