Found this on my friend's Pinterest page who found it on Paula Deen's website. I didn't add the onion to mine. In the future I'll use it as a side dish, I took it to work for lunch today and it's kind of a bland lunch by itself.
1 pound cucumbers (about 2 cucumbers), peeled and thinly sliced
1 pint cherry tomatoes, halved
1/2 Vidalia onion, very thinly sliced
2 tablespoons chopped fresh parsley leaves
1 tablespoon apple cider vinegar
1 tablespoon olive oil
Salt and freshly ground black pepper
In a large serving bowl, toss together the cucumbers, cherry tomatoes, onion, parsley, vinegar, olive oil, salt, and pepper, to taste. Let the salad stand for 10 minutes before serving.
