A focaccia is an Italian flatbread and with this basic recipe you can easily bake it yourself. The nice thing about this focaccia recipe is that you can decide for yourself which topping you put on the bread. Do you go for the classic version, with rosemary and coarse sea salt, or for the one with tomatoes and olives, or do you go all out with different types of cheese and grilled vegetables, for example? You can vary endlessly with the topping and you should definitely do that!
