Steps:

• Combine 1/2 cup soy sauce, rice vinegar, 1 tablespoon chives, sesame seeds, and chile sauce in a small bowl. Set aside.
• Mix pork, garlic, egg, 2 tablespoons chives, soy sauce, sesame oil, and ginger in a large bowl until thoroughly combined. Place a dumpling wrapper on a lightly floured work surface and spoon about 1 tablespoon of the filling in the middle. Wet the edge with a little water and crimp together forming small pleats to seal the dumpling. Repeat with remaining dumpling wrappers and filling.
• Heat 1 to 2 tablespoons vegetable oil in a large skillet over medium-high heat. Place 8 to 10 dumplings in the pan and cook until browned, about 2 minutes per side. Pour in 1 cup of water, cover and cook until the dumplings are tender and the pork is cooked through, about 5 minutes. Repeat for remaining dumplings. Serve with soy sauce mixture for dipping.

Steps:

• Heat oven to 350°F. In large bowl, mix all ingredients except biscuits and sweet-and-sour sauce.
• Remove 1 can of biscuits from refrigerator just before filling (keep remaining can of biscuits refrigerated). Separate each biscuit into 3 layers. Press each layer into 3 1/2-inch round, being careful not to tear dough.
• Spoon 1 rounded tablespoon of pork filling on center of each dough round. Bring all sides of dough up over filling, stretching gently if necessary, and gather in center above filling to form a dumpling; press gathered dough to seal. On ungreased large cookie sheet, place 24 dumplings 2 inches apart.*
• Bake 17 to 27 minutes or until thermometer inserted in center reads 160°F** and sides and tops of dumplings are golden brown. Repeat to make remaining dumplings. Serve warm with sweet-and-sour sauce.
