Method:

1. First, prepare the vegetables. Cut up tomatoes into wedges, cucumber into thick slices, and thinly slice the onion.

2. Place the vegetables into a bowl, then add the cubes of feta cheese, olives, oregano, and optionally, capers.

3. Season with salt, to taste, and pour over with olive oil. And, if using red-wine vinegar, first, make a dressing with olive oil, before you add it to the salad.

4. Now, toss the salad to combine and serve.
