Thank you for the link to the recipe!
This weekend I am going to a small gathering of women and don't know whether there are vegetarians among them. I bought pita bread at the market and thought it would be good to bring, but what to go with it? I now will make this tzatziki and a wheat berry and barley salad - I wanted to make tabooleh but I don't have those ingredients, so this salad is similar, with the whole grains, parsley, onion, garlic, and tomato and a few cut up dates. I haven't made this recipe before so wish me luck!
