Bring a large pot of salted water to a boil over medium heat. Add your choice of pasta and cook according to package instructions until al dente. Stir occasionally to prevent sticking. Once done, drain the pasta and rinse it under cold water to stop the cooking process. Set aside.

If you're making homemade pesto, combine fresh basil leaves, garlic, pine nuts, Parmesan cheese, and olive oil in a food processor. Blend until you get a smooth sauce. Adjust seasoning with salt and pepper. If you're using store-bought pesto, ignore this step!

In a large mixing bowl, combine the cooled pasta, pesto, halved cherry tomatoes, and mozzarella balls. Toss everything expertly until the pasta is fully coated with the pesto, and the tomatoes and cheese are well distributed.

Taste the pasta salad and add salt and pepper as desired.

Garnish with fresh basil leaves and a sprinkle of grated Parmesan. Serve this dish chilled or at room temperature for the best flavor experience!
