Direction :

1. Bring a large pot of water to a boil. Season well with kosher salt. Add pasta and cook till al dente, about 9 minutes or about 2 minutes less than what package instructions suggest. (Pasta will continue cooking as it is tossed with the other ingredients so it’s best to undercook it a little bit.) Drain pasta, reserving a cup or more of the pasta cooking liquid. Do not rinse.
2. Heat olive oil in a large skillet over high heat. Add the cherry tomatoes and cook for 30 seconds. Add pasta and pesto. Cook 1 minute, stirring to coat pasta with the pesto. Taste. Adjust with more salt, pepper, pesto, or a few tablespoon of the reserved pasta cooking liquid to make it saucier. Add the mozzarella. Stir to incorporate. Add the fresh basil and remove from the heat.
3. Divide pasta among bowls and sprinkle each with some fresh shavings of Parmigiano. Crack the pepper over top and serve.
