Pissaladière is a dish of flatbread with toppings from the region of Provence and the French city of Nice. It is often compared to pizza. The dough is usually a bread dough thicker than that of the classic pizza Margherita, and the traditional topping in Nice usually consists of caramelised onions, black olives and anchovies.

A flatbread is bread made usually with flour; water, milk, yogurt, or other liquid; and salt, and then thoroughly rolled into flattened dough. Many flatbreads are unleavened, although some are leavened, such as pita bread.
