Cook the pasta: In a large pot, bring plenty of salted water to a boil. Add the Creste di Gallo and cook according to the package instructions until al dente. Drain, reserving a bit of the cooking water.
Prepare the sauce: In a large skillet, heat the extra virgin olive oil over medium heat. Add the sun-dried tomatoes and sauté for a couple of minutes, stirring occasionally.
Combine the pasta and pesto: Add the cooked Creste di Gallo to the skillet with the sun-dried tomatoes. Pour in the pesto sauce and mix well, adding a bit of the reserved pasta cooking water if necessary to make it creamier.
Serve: Plate the Creste di Gallo and garnish with toasted pine nuts, grated Parmigiano Reggiano, and fresh basil leaves. Adjust with salt and pepper to taste.
