Cook pasta according to directions. Rinse with cold water.
Add vegetables, beans and cilantro to the pasta. Stir until combine.
Toss in cheese.
Combine the ranch dip with the Greek yogurt and stir well. Add 1-2 cups of the ranch dressing to pasta salad.
Refrigerate for at least one hour before serving.
Notes
I added only 1 cup of the ranch dressing to the pasta salad since we were not eating it immediately and added the remaining 1 cup right before serving.
