Pita, a Middle Eastern daily bread, gets its hallmark hollow center while it bakes. In the hot oven, steam pushes the top from the bottom, leaving a convenient pocket in the middle. Pita can be filled with or wrapped around all sorts of fillings. It can be cut into wedges and used as a dipper, toasted or not. Some typical fillings include greek souviaki (grilled lamb or pork chunks served with cucumber sauce); falafel (fried Middle Eastern grain patties); and hummus, a spread made of ground garbanzo beans (chickpeas) and tahini.
