Begin by cooking the pasta according to the package instructions. When finished, drain and rinse under cold water to stop the cooking process. Set aside.
In a large mixing bowl, combine the cherry tomatoes, cucumber, red bell pepper, red onion, black olives, mozzarella balls, and chopped basil.
In a separate small bowl, whisk together the olive oil, lemon juice, lemon zest, salt, and pepper until well combined.
Add the cooled pasta to the bowl of vegetables and toss to combine.
Pour the lemon vinaigrette over the pasta salad and mix gently until everything is well coated.
Cover the salad with plastic wrap or transfer it to an airtight container. Refrigerate for at least 30 minutes to allow the flavors to meld.
Serve chilled, garnished with additional basil leaves if desired.
Notes
Serve in a large, shallow bowl for a beautiful display, and sprinkle some extra chopped basil and a few halved cherry tomatoes on top for an extra pop of color.
