three cheese pasta (or cleaning out the cheese drawer pasta)

I made up this cheesy pasta sauce from three cheeses I had in the refrigerator that needed to be used up. I don't even know what one of them was. I bought it at Whole Foods a little while ago when I wanted something new and I can't remember what kind of cheese it was. For now, we will call it "mystery cheese." The point of this recipe is just a way to use up leftover cheese.
