Serve this on a large fancy serving dish and sprinkle generously with salt and pepper. I have served this many times at my dinner parties... not only is this beautiful to look at, it is absolutely delicious!. Olives can be replaced with capers if desired, and oregano can be replaced with fresh basil. Plan ahead this salad needs to be left out at room temperature for 1 hour or refrigerated for 3 hours before serving. Another variation for this salad is layer mozzarella cheese in between the veggies and omit the feta, it is just as good both ways, but I have to say that the feta is better. Be certain to only use an firm English cucumber for this, otherwise the salad will get watery. This salad should serve up to 6 people, increase all ingredients if serving more. If you are serving this chilled I strongly suggest to let the salad sit out for 1 hour at room temperature before serving, the tomatoes will soften and taste better, tomatoes really should not be refrigerated, they permanently loose their taste and texture. You will love this salad!
