If you like nuts, here is a very easy recipe for a pasta sauce that will serve two persons. In this recipe, Walnuts can be replaced by unsalted peanuts.
In a bowl, grind a 1 - 1 1/2 cup of walnuts. To grind them, I am using a coffee grinder. Add a teaspoon of minced garlic, two tablespoons of olive oil, a tablespoon of parsley, season with salt and add 4 generous spoons of sour cream. Mix all the ingredients and it is done! I suggest you heat the sauce for one minute in the microwave before serving. Isn't this easy?
Enjoy (I do)!
