First you’ll need to chop the veggies. The cucumbers don’t need to be peeled, but you can peel them if you’d like. You can also remove the seeds if desired. Chop or slice the cucumber into even pieces. Place the chopped cucumbers in a large salad bowl.
Cut the tomatoes into halves or quarters and add them to the cucumbers.
Finely dice the red onion and add it in with the tomato and cucumber.
Chop or slice the black olives if desired. Place the olives and feta in the bowl with the cucumbers and tomatoes.
Next we’re going to make the salad dressing –
In a small bowl whisk together the olive oil, balsamic vinegar and dried oregano until well mixed.
Add the dressing to the vegetables and stir or toss until everything is evenly coated.
Cover and chill for 30 minutes to allow the flavors to meld.
Store any leftovers refrigerated in an airtight container.
