This cold pesto pasta salad will cool you off on a summer day. Fresh tomatoes and roasted red peppers add a pop of bright color and juiciness here, but any of your favorite pasta-salad veggies, like blanched broccoli and fresh bell peppers, would be delicious too.
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.
