Bring a large pot of salted water to a boil. Add the tortellini and cook according to package instructions until al dente. Drain and rinse under cold water to cool.

In a large mixing bowl, combine the cooked tortellini, cherry tomatoes, cucumber, bell pepper, spinach, and mozzarella balls.

Pour the Italian dressing over the salad and toss gently to combine. Sprinkle with fresh basil before serving.
