My version:
1 package multi-colored spiral pasta, cooked
1 package frozen mixed vegetables (I like Fiesta Blend)
Your favorite bottled creamy dressing (I personally like something on the sweet side like Johnny's Jamaica Mistake) enough to moisten ingredients "to taste"
Mix together, cool, enjoy.
You can add extras as you like. Sliced ripe olives; chopped sweet onion; chopped artichoke hearts, cheese cubes, shrimp, etc.
