In a large mixing bowl, slice the cucumbers into thin rounds, halve the cherry tomatoes, and thinly slice the red onion. Gently mix these vibrant vegetables together until they are well distributed.

In a separate bowl, whisk together ½ cup of apple cider vinegar, ¼ cup of olive oil, 1 tablespoon of granulated sugar, ½ teaspoon of salt, ¼ teaspoon of freshly cracked black pepper, and 1 teaspoon of oregano until well combined.

Drizzle the prepared dressing over the vegetable mix in your large bowl and gently toss until completely coated.

Cover the bowl with plastic wrap or a lid and refrigerate for at least 30 minutes to allow flavors to meld.

Before serving, toss the salad again and sprinkle with freshly chopped parsley or dill for garnish.
