Key to success: Do not skip the salting step. Even 10 minutes makes a visible difference. After rinsing, dry the cucumbers extremely well – a dedicated salad towel works best. Add the feta last to keep it in distinct, creamy chunks. For best texture, dress the salad no more than a few hours before serving. Store components separately for meal prep: pressed cucumbers (lined with paper towels), vinaigrette in a jar, feta and herbs in their own containers. Assemble just before serving. Lasts 3-4 days stored this way.
