2) In a medium skillet heat the olive oil over medium heat. Add the garlic and saute until fragrant, about two minutes. Add the tomatoes, salt, and pepper. As the tomatoes cook and soften, smash them with a fork. Continue to cook until the tomatoes make a chunky style sauce, about four minutes. Transfer the tomato sauce to the bowl with the pasta. Toss to combine. Add the basil leaves and mozzarella. Stir to combine. Add the reserved pasta water, 55ml at a time, until the pasta is moist. Serve.
