Cong you bing (/ˈtsʊŋ joʊ ˌbɪŋ/; Chinese: 蔥油餅; pinyin: cōngyóubǐng; lit. 'scallion oil pancake'), also known as scallion pancake or green onion pancake, is a Chinesesavory flatbread made with wheat dough and minced scallions. 

The unleavened dough is folded repeatedly into layers, with oil and green onions added between each layer. Then it is pan-fried, which gives it crisp edges and a chewy texture. Many layers make up the interior, contributing to its chewy texture.^[1]Variations exist on the basic method of preparation that incorporate other flavors and fillings.

Scallion pancakes are served both as a street food item and as a restaurant dish. They are also sold commercially, either fresh or frozen in plastic packages (often in Asian supermarkets).
