Salt and boil water in a medium saucepan. Once the water has reached a rolling boil, add pasta. Stir occasionally. Once cooked to al dente, remove from heat and drain.
While waiting for water to boil, prepare all remaining ingredients. Add ingredients to a large bowl or container.
Once the pasta has been cooked and drained, add to the bowl of ingredients. Stir well. If using a lid with a container, secure the lid and shake vigorously to incorporate all ingredients.
Place in refrigerator until ready to serve. Before serving, add additional dressing and feta cheese if the pasta has dried out, and stir well.
