Ingredients

  • 2 garlic cloves, crushed under a knife and peeled
  • 13 cup pine nuts or 13 cup walnuts or 13 cup almonds
  • 12 cup freshly grated parmesan cheese (or a combination) or 12 cup romano cheese (or a combination)
  • 3 cups packed fresh basil leaves, well rinsed and dried in a salad spinner
  • 12 cup extra virgin olive oil, plus more to cover the pesto
  • salt
  • fresh ground black pepper
  • 12 lb green beans, trimmed and cut into 1-inch lengths (preferably flat Romano beans)
  • 2 12 lbs red potatoes, scrubbed
  • 2 tablespoons red wine vinegar
  • 12 cup extra virgin olive oil
  • salt
  • fresh ground black pepper
  • chopped fresh basil or parsley

Method

  • Make the pesto--with the machine running, drop the garlic through the feed tube of a food processor.
  • Add the nuts and cheese, and process until the nuts are finely chopped.
  • Add the basil.
  • With the machine running, gradually add the oil, scraping down the sides of the work bowl as needed, to make a thick paste; season with salt and pepper to taste.
  • Transfer the pesto to a shallow container and smooth the pesto; pour a thin film of olive oil over the pesto to discourage discoloration.
  • Cover the container and refrigerate until ready to use (the pesto can be stored for up to 3 weeks, covered and refrigerated; bring to room temperature before using).
  • Salad--bring a large pot of lightly salted water to a boil over high heat.
  • Add the green beans and cook until tender, about 4 minutes.
  • Using a skimmer or wire strainer, remove the green beans from the water and transfer to a bowl of cold water; drain and pat dry with paper towels.
  • Add the potatoes to the water and return to a boil.
  • Decrease the heat to medium and simmer the potatoes until they are tender when pierced with a sharp knife, about 25 minutes.
  • Drain the potatoes in a colander and rinse under cold water until easy to handle.
  • Slice the warm potatoes into 1/2-inch thick rounds and transfer to a medium bowl.
  • Whisk 3 tablespoons pesto, the vinegar, and oil together.
  • Pour over the potatoes, add the green beans, and mix.
  • Season with salt and pepper to taste.
  • Cover with plastic wrap pressed directly on the surface of the salad and cool.
  • Sprinkle with the basil and serve at room temperature.
