This recipe originally called for the rice to be rolled in vine leaves, but I couldn't find those so I used cabbage leaves instead and it worked out just fine. However, if you can find vine leaves their darker colour would make for a nice contrast with the tzatziki. To speed this recipe up, you can use the store bought tzatziki, although I think the homemade stuff is much better!
Until we went to Greece, we always made Greek salad with lettuce. Now we know this is the way they do it in Greece, and it's so much better (not to mention simple)! The amounts used are rough guides, you can adjust them to your taste.
