Place a pasta pot with water on to boil. Add one teaspoon salt and one tablespoon olive oil. Once it starts boiling add the peeled and diced potato to the water.

Cook for 4 minutes. Add in pasta. Cook 8 minutes then add in trimmed fresh green beans. Cook until pasta is al dente. Strain pasta but reserve some pasta water to help when mixing the pesto and set aside.

Either with a mortar and pestle or a food processor. Blend together the one teaspoon salt, basil, garlic, cheeses, 1/2 cup olive oil, and pine nuts. If allergic to nuts just remove the nuts. If it's too thick add more olive oil.

In a serving bowl, add about a 1/3 cup pasta water and two heaping spoonful's of pesto. Add pasta, potatoes, and green beans. Toss well. Serve!
