Suchlike Panzanella - the Italian bread salad, Cretan rusk salad (Kρητικός ντάκος) is based on bread.
In fact, it is a large barley rusk topped with chopped tomatoes, crumbled Feta or Mizithra cheese and some olive oil. People in Creta and especially the sailors, used to eat a lot of rusks. Main reasons - rusks are lighter than fresh bread and more of them could be laded on the ships. They are unexpensive and long-lasting and do not get mouldy which is important on any island where every product is limited. Cretan dakos is still one of the traditional Cretan salads. If you do not have rusks on hand, you can use toasted or grilled bread - taste is nearly the same.
