Heat oven to 350. In large bowl mix the first nine ingredients until combined. 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 chicken 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.
