In a medium bowl, whisk together Greek yogurt, mayonnaise, red wine vinegar, and lemon juice. Gradually drizzle in olive oil while whisking until smooth.

Incorporate dried herbs, honey, and Parmesan cheese, mixing thoroughly. Adjust seasoning as needed.

In a large mixing bowl, add chopped romaine lettuce, halved cherry tomatoes, sliced cucumber, and thinly sliced red onion.

Add halved pepperoncini and pitted Kalamata olives, then crumble feta cheese over the top.

Toss gently to combine, taking care not to crush the feta.

Drizzle dressing over the salad right before serving and toss to coat.

Add croutons just before serving to maintain their crunch.
