Gather all ingredients.

Bring a large pot of lightly salted water to a boil. Cook pasta in the boiling water, stirring occasionally, until tender yet firm to the bite, about 10 to 12 minutes; rinse under cold water and drain.

Whisk Italian dressing and salad spice mix together until smooth. Combine pasta, tomatoes, bell peppers, and olives in a salad bowl.

Pour dressing over salad and toss to coat.

For the best flavor, refrigerate the pasta salad for 8 hours to overnight.

Enjoy!
