Wash cucumbers and slice in half lengthwise. Cut the cucumber into small 1/2 - 1 inch sections,and toss them into a large mixing bowl with the red onion. Set aside.
In a separate, smaller bowl whisk together the yogurt, dill, parsley, apple cider vinegar, garlic powder, salt, and pepper. Pour the yogurt mixture over the cucumber and onions and toss to combine.
