Ingredients
  

  • 1 pound whole-wheat penne or rotini pasta
  • 2 cups lightly packed fresh basil leaves plus more for garnish
  • 1/2 cup lightly packed flat-leaf parsley leaves
  • 1/2 cup chopped walnuts toasted
  • 1/2 cup grated Parmesan cheese
  • 1 clove garlic grated
  • 1 tablespoon lemon juice
  • 1 teaspoon salt
  • 1/4 teaspoon ground pepper
  • 1/2 cup extra-virgin olive oil
  • 1 medium tomato chopped
  • 1/2 cup chopped jarred roasted red peppers rinsed

Instructions
 

  • Bring a large pot of salted water to a boil over high heat. Cook the pasta according to the package instructions, then drain it and rinse with cold water to stop the cooking process.
  • While the pasta cooks, combine the basil, parsley, walnuts, Parmesan cheese, garlic, lemon juice, salt, and pepper in a food processor. Pulse the mixture until finely chopped, scraping down the sides as needed.
  • With the food processor running, slowly drizzle in the olive oil until the pesto becomes smooth and well combined. Taste and adjust seasoning if necessary.
  • Transfer the prepared pesto to a large mixing bowl. Add the cooked pasta, chopped tomato, and roasted red peppers. Toss until the pasta is evenly coated with the pesto.
  • Garnish with additional basil leaves if desired and serve immediately. You can also refrigerate the salad for up to 1 day and serve chilled.

Notes

Store leftovers in an airtight container in the refrigerator for up to 3 days. To add variety, swap walnuts for almonds or pine nuts, or include grilled chicken or shrimp for extra protein.
