In a small mixing bowl, combine ½ cup olive oil, ¼ cup apple cider vinegar, 2 teaspoons Italian seasoning, 1 teaspoon granulated sugar, 1 teaspoon garlic powder, ½ teaspoon salt, and ½ teaspoon black pepper to make the dressing. Set aside.
Boil 8 ounces farfalle pasta in salted water according to the package for al dente. As soon as the pasta is ready, drain the pasta into a colander and run cold water over the pasta for 1 to 2 minutes to cool it rapidly.
Combine the pasta and dressing in a large serving bowl. Then gently mix in the ½ medium red onion (sliced), 8 ounces cherry tomatoes (halved), 1 English cucumber (chopped), 4 ounces mozzarella pearls, 4 ounces salami slices (sliced), ½ cup kalamata olives, and ¼ cup chopped fresh parsley. Toss together until evenly combined and coated in dressing.
Allow the pasta salad to chill in the refrigerator for 15 to 20 minutes before serving. Enjoy!
