Pesto potato salad sounded a bit weird, though all the ingredients are among my favorites: http://smittenkitchen.com/blog/2009/06/pesto-potato-salad-with-green-beans/. I planned to go for the traditional pasta instead, but then it turned out Sandis already had pasta for lunch. What`s in between pasta and potatoes? Potato dumplings! Otherwise, the recipe is from the link above. I also added some salad leaves, as they were withering in the fridge. Crumble feta on top to make the dish more filling.
