Wild mushrooms, caramelized onions, creamy ricotta, tangy cheese, fresh herbs make this a great dish. Now I prefer whole wheat manicotti if you can find it. I found some at Whole Foods which I love, but if not, good ol' Ronzoni or Muellers or any brand will work just fine. To me it is just a nice option to the tomato based manicotti or that with beef or chicken. I just enjoy the change of having a lighter vegetarian dish now and then even though this has a rich cream sauce. You can certainly use a heavy cream vs milk, or even a combination of the two if you want even a thicker sauce, but the the comibination of the wild mushrooms and the Asiago make this a rich dish.
