Toss 8 ounces green beans with olive oil, salt and pepper on a baking sheet. Quarter 1 pound small red-skinned potatoes; toss with olive oil, salt and pepper on a separate baking sheet. Roast at 425 degrees F until the vegetables are browned, 15 minutes for the green beans and 25 to 30 minutes for the potatoes; let cool. Cook 8 ounces gemelli as the label directs. Drain, then toss with 1/4 cup olive oil and the zest of 1 lemon; let cool. Add the beans and potatoes, the juice of 1/2 lemon, 1/2 cup chopped basil and 1/4 cup toasted pine nuts; toss. Top with shaved Parmesan.
