This pesto salad is best with either 2/3 cilantro and 1/3 mint (C: too minty) or all arugula or the really oily pesto one buys in stores if one does not have a produce fixation. Boil one pound of potatoes until tender- try to use a sweetish potato, like white potatoes or German butterballs or Yukon golds. Destem one half pound green beans and cut into inch long pieces. Blanch the green beans until tender- about two minutes.
Slice the potatoes into bite sized chunks. Add green beans. Dress with olive oil, lemon juice, and 1/4 cup pesto. (I suppose you could use less pesto, but at this point I'm just dumping it into everything. Oil and lemon are to taste- a dollop and a half lemon, probably.)
It's a pretty good potato salad, but I like all potato salads. Obviously.
