What to make with sour cream and mushrooms--> please answers with ravioli fillings!?

Make squash and potato raviolis with a sour cream and mushroom sauce. |Steam or bake the squash until it can be pureed. Boil and mash the potato. add some cream cheese and salt and pepper and a hint of sage if you have any. Use the eggs to make the pasta. Saute the mushrooms with some onion and garlic and make a cream sauce with er and flour and the sour cream. Use the parmesan in the cream sauce to finish it. Just barely cook the ravioli until they float and then finish cooking them in the cream sauce.
