01 - Bring a large pot of salted water to a rolling boil. Cook penne pasta according to package directions until al dente. Drain thoroughly, reserving about 1/2 cup pasta cooking water.
02 - In a large serving bowl, add the halved cherry tomatoes, minced garlic, and torn basil leaves.
03 - Add the warm, drained penne to the bowl. Drizzle with extra virgin olive oil and toss gently to combine. If the mixture appears dry, incorporate a small amount of reserved pasta water.
04 - Gently fold in the fresh mozzarella pieces, ensuring they warm through and soften from the residual heat of the pasta.
05 - Taste and season with salt and freshly ground black pepper. Stir in chopped parsley if desired.
06 - Transfer to individual plates or a platter. Drizzle with balsamic glaze and garnish with additional basil, if preferred. Serve immediately, either warm or at room temperature.
