Add pasta to boiling water and cook about 10 minutes, or until done. Drain, rinse, and cool. Blend mayonnaise, apple cider vinegar, salt, and pepper. Combine dressing, veggies, and pasta, adding additional mayonnaise and vinegar to taste if needed.
To turn this into a main dish salad, add two 6-ounces cans tuna or salmon, drained and flaked.
