Heat a large pot of water and add the coarse sea salt when it begins to boil.
Meanwhile, cut your cherry tomatoes in half (or roughly chop your large tomatoes). If you do not have bocconcini size mozzarella, cut mozzarella into cubes. Roughly chop the basil. Place the tomatoes, mozzarella, and basil together in a bowl.
Add salt, black pepper, and extra virgin olive oil to the bowl. Mix well to coat all of the ingredients then taste and adjust the seasoning if necessary. Let this sit while you cook the pasta.
When the water is boiling, add the pasta and cook until al dente. Drain the pasta.
Rinse the pasta under cold water to stop the cooking process. Strain the pasta then add it to the bowl with the tomatoes and mozzarella. Carefully stir everything together and let it reach room temperature prior to serving or place it in the refrigerator and serve cold.
