All cooks have a few basic recipes that they turn to again and again over the course of a year. Potato and green bean salad is one of mine. I make it different ways depending on the season and my mood. It's very good dressed with just olive oil and lemon juice, but it becomes absolutely superb when bound with homemade Green Goddess. If you're familiar only with the bottled version of this dressing, you must try my recipe, which is based on the original, invented in the 1920s by the great San Francisco chef Victor Hirtzler.
