Just made/had that tonight. From a mix (from Lebanon -- just add water, wait an hour, roll, then fry), but still pretty good -- bought it at a Turkish market, along with the accompanying Tahini. Standing in for the Tzatziki was a Greek yogurt dip w/ similar flavorings (cucumber/dill/feta -- not enough cuc, too much feta), with plain Greek yogurt added into it to mellow it out a little. Served in whole wheat pitas with sliced tomato (didn't have lettuce). Good stuff!
