Chicken Pasta Salad

I made this for the going away potluck for the Gunns and Andersons this week. This is another one from Recipe Shoebox.

Ingredients
1 lb. cooked, shredded chicken (I usually use can of Costco chicken)
1 lb. cooked rotini noodles (or bow tie)
2 heads broccoli, finely chopped
1 red pepper, chopped
1 green pepper, chopped
1/3 onion, chopped
1 can sliced olives
1 cup shredded cheese (optional)
1/3 - 1/2 cup ranch dressing (don't skip this--it's what holds it all together)

Dressing:
2 envelopes dry Italian dressing mix
6 Tbs. apple cider vinegar
4-1/2 Tbs. water
3/4 cup oil (you can reduce this some)

Combine cooled chicken, chopped vegetables, and olives. Whisk together dressing ingredients and pour over vegetables and chicken. Mix together. Add ranch dressing and cheese. Refrigerate 1 hour before serving. Serves 8 - 10.
