Walnut Pesto Pasta Salad

Bring a large pot of water to a boil over high heat. Cook pasta according to package directions. Drain and rinse with cold water.

Meanwhile, combine basil, parsley, walnuts, Parmesan, garlic, lemon juice, salt and pepper in a food processor. Pulse, scraping down the sides as necessary, until finely chopped. With the motor running, slowly drizzle in oil.

Transfer the pesto to a large bowl and add the pasta, tomato and peppers. Toss to coat. Top with more basil, if desired.
