This is a recipe I found when I was looking for something different to do with pasta. I adapted a basic pasta primavera to a livelier version. It is a little like a stroganoff sauce but spicier and not so creamy. It is also a very healthy recipe in that there's littlle fat - unless you use a load of parmesan. Although very quick and easy to make this is still quite an elegant dish. Basically you can add other vegetable in season. It is particularly nice to adda little black truffle shaving to the sauce but as this is an expensive ingredient it is not at all essential.
