Cook pasta according to directions in salted water. Drain and rinse under cold water until completely cooled. Shake off as much excess water as possible.

In a large bowl, whisk together the mayonnaise, balsamic vinegar, olive oil, and kosher salt and black pepper to taste.

Add the drained and cooled pasta, fresh mozzarella, tomatoes, and basil to the bowl with the dressing. Stir to coat.

Drizzle with more olive oil and balsamic, and top with fresh cracked pepper before serving, if desired.
