Prep 14 mins, Cook 26 mins
1 large bunch basil (about 4 ounces)
1/3 cup raw walnuts
½ cup freshly grated Parmesan cheese, plus 1 tablespoon for topping
2 large cloves garlic, peeled 
Juice of 1 lemon
1/4 cup plus 1 tablespoon extra-virgin olive oil
½ pound whole-wheat penne rigate (or other pasta)
1 tablespoon toasted pine nuts or slivered almonds, for garnish
1. Bring a large, salted pot of water to boil.
2. Rinse basil and spin dry. Discard stems. Place leaves in food processor and pulse until finely chopped. Transfer to bowl. Place walnuts, cheese, and garlic in food processor and pulse until finely chopped. Return basil to food processor and, while running, add lemon juice and ¼ cup olive oil in a slow stream until incorporated. Season with sea salt.
3. Add penne to boiling water and cook al dente, stirring occasionally to prevent sticking. Drain and toss with about two-thirds of the pesto, or to taste. Serve immediately, topped with Parmesan cheese and toasted nuts.
