ARUGULA PESTO SAUCE
3 cups packed arugula, washed and spun dry
1/3 cup toasted pine nuts, cooled
1/2 cup freshly grated Parmesan cheese
1/2 teaspoon salt
1 large garlic clove, chopped
3 tablespoons olive oil
1/4 cup hot water plus additional if desired
In a food processor pulse together all ingredients except oil and water until arugula is chopped fine. With motor running add oil in a stream, blending mixture until smooth. Sauce may be made up to this point 1 week ahead and chilled, its surface covered with plastic wrap. Bring sauce to room temperature to continue. Stir in 1/4 cup hot water plus additional for thinner consistency if desired.
