Fresh herbs and vegetables are the focal point of this Greek-inspired meal that includes crisp romaine salad with caper berries, tomatoes, and feta.
Make the dressing: Whisk together vinegar, salt, and oregano, and season with pepper. Add oil in a slow, steady stream, whisking until emulsified.
Assemble the salad: Arrange lettuce on a platter. Scatter olives, peperoncini, caper berries, tomatoes, cucumbers, onion, and feta over top. Drizzle with dressing.
