Cook pasta according to package directions; drain and rinse with cold water. Rinsing with cold water will help prevent it from sticking together. Set aside and allow to cool and dry completely. When dry, add the beans, corn, tomatoes, green onions, onion and cilantro. In a separate bowl, combine all the dressing ingredients and add to pasta mixture.
Stir together until everything is evenly coated in sauce. You can either stir the Feta cheese into the salad or use it as a garnish on top. Taste and adjust any ingredients as needed. Refrigerate until ready to use. This is best served on the day it is made. Serves 8-12 people.
