'Komplet' means 'the full set' — bread, kajmak, egg and pretop together — and a proper one is heavy enough to replace lunch as well as breakfast.
A lepinja flatbread is split open, filled with kajmak and a beaten egg, baked, then drenched in pretop, the drippings from roast meat. It's served hot on a plate from kafanas as a filling breakfast, often with roast meat on the side.
