Banitsa in any form is part of a traditional Bulgarian breakfast. Banitsa is a greasy pastry dish that can be purchased in all Bulgarian bakeries. Its standard filling is a feta-like white cheese. Other fillings include onions, cabbage, spinach, mushrooms or pumpkin. Sweeter versions are filled with apples or walnuts. Bulgarians combine banitsa with boza, a thick fermented wheat drink.
