Fiesta Chicken Pasta Salad

Thanks to the Sister's Cafe -- this salad looks simple and delicious!!

1 pkg Hidden Valley Fiesta Ranch dip mix
½ c. oil
½ c. vinegar
1 lb cooked, shredded chicken (about 1 ½ to 2 breasts)
3/4 box garden rotini
1 can black beans
1 can black olives, halved
2 -3 tomatoes, chopped
Frozen corn

Mix dressing mix, oil, and vinegar in small bowl and set aside. Combine chicken, cooked pasta, beans, olives, and tomatoes in large bowl. Add dressing and frozen corn about 20 minutes before serving. Be sure to toss again just before serving, as the dressing will seep to the bottom.
