Brilliant green and exploding with the flavors of summer, this variation on the classic pasta sauce took first place in out cook-off because of its secret ingredient: a sprig of parsley. Pesto means "pounded" in Italian, but we use a food processor for its speed and ease instead of the traditional mortar and pestle.
In a food processor, combine the basil leaves, parsley, and garlic. Add the salt, pine nuts, and olive oil. Blend to a creamy butter consistency. Add more oil, if necessary, and pepper to taste. Finally, add the Parmesan cheese.
Cook the pasta according to the package directions. Drain it in a colander, then transfer to a large serving bowl. Toss with the pesto and garnish with chopped tomatoes, if desired. Serves 8 to 10.
