This is the perfect quick and easy summertime side dish that is always sure to be a crowd pleaser.
Bring a large pot of lightly salted water to a boil. Then add the pasta, and cook until al dente, about 8-9 minutes. Drain and rinse under cold water, draining again.
While the pasta cooks, mix together the mayonnaise, vinegar, salt and pepper in a small bowl.
Once the pasta is drained, in a large bowl, gently toss it with the dressing. Then fold in the carrots, celerly, bell pepper, parsley and the olive oil. Season with salt and pepper as needed. Then refrigerate for at least 2 hours before serving. Give a gentle toss again before serving.
