I had a very tasty pasta dish at a local Italian restaurant early this year. I have made it quite a few times but am starting to forget the recipe. Here it is before it's a lost memory. . .
Sautee mushrooms and a minced garlic clove or two in butter and olive oil then add lots of fresh spinach. Once the spinach wilts, add heavy cream (oh, about 1 cup) and parmesan cheese (about 1/2 -3/4 cup). Stir until the cheese melts, about 3-4 minutes, and allow the sauce to thicken a bit. This recipe also has pine nuts. You can skip them if you want but they make a nice addition. Add them with the cream or after the cream
