Separate each can of crescent dough into 8 triangles. Slightly stretch corners of shortest side of each triangle to make longer. Cut each triangle in half lengthwise to make 32 narrow triangles. Place on 2 ungreased cookie sheets. Place chile at shortest side of triangle. Spoon heaping tablespoon potato mixture into chile. Roll crescent from shortest side to point, wrapping around filled chile; press gently to seal. Repeat to use up dough, chiles and potato mixture.
