Cook pasta according to package directions.

Using a large mixing bowl add all other ingredients except the Italian dressing while waiting on pasta to cook.

Drain pasta and add to bowl. Add dressing in increments so as to not drown mix. Mix well. Can be served immediately or chilled.

P.s. For those who don't like the raw onion taste you can add it to the pasta during the last 3 minutes to blanch it some.

Enjoy.
