1 package rotini pasta noodles, cooked per package directions and cooled
2 cups cherry tomatoes, halved
1/2 a medium red onion, diced
1/2 a red bell pepper, diced
1/2 a green bell pepper, diced
1 3.8 ounce can sliced black olives
Half a package of turkey pepperoni (or regular if you prefer), sliced into strips
1 bottle zesty Italian dressing

Cook the pasta according to the package directions. Set aside until cool.

In a large bowl, combine the diced onion, diced peppers, black olives and sliced pepperoni. Add the cooled pasta. Pour the Italian dressing over the pasta, and mix until well combined. Refrigerate for several hours to let the flavors meld together.
