Combine first four ingredients (through salt and pepper) in a large bowl. Place 1 tablespoon of buffalo chicken mixture into the center of a wonton wrapper. Brush water along all edges of wonton wrapper for sealing. Bring two corners of wrapper together in a point and then seal edges of wrapper closed. Form filled wrapper into a crescent at the bottom to help the potsticker stand during and after cooking. Place on a baking sheet covered with a damp towel to prevent wrappers from drying out before cooking.
