Begin by bringing a large pot of salted water to a rapid boil. Add your chosen pasta and cook according to package instructions until al dente, usually about 8-10 minutes. Once cooked, drain and rinse it under cold water until cool.

While the pasta is cooling, prepare your vegetables by dicing fresh bell peppers, cucumbers, and cherry tomatoes into bite-sized pieces.

In a separate bowl, combine mayonnaise and sour cream until smooth, adjusting to taste with salt and pepper.

Once the pasta is cooled, combine the pasta, diced vegetables, and any protein add-ins in a large mixing bowl. Pour the dressing over and toss to coat.

Cover and refrigerate for at least 30 minutes to allow the flavors to meld before serving.
