Step 1

To make the dressing, in a large bowl whisk together olive oil, red wine vinegar, Dijon mustard, oregano, and salt and pepper to taste (I like 1/2 teaspoon salt and 1/4 teaspoon pepper).

Step 2

Add the sliced cucumbers and red onion and marinate at least 5 minutes or up to 30 minutes.

Step 3

To the bowl with the dressing, add chickpeas, tomatoes, Kalamata olives, and parsley. Toss to combine and sprinkle with feta cheese.
