Blend cream cheese & 3 tablespoons butter. Add chicken and next five ingredients--fold together until blended. Unroll crescent roll dough and divide into rectangles (4 per can) pressing together the diagonal perforations.
3) Place rounded 1/2 cup chicken mixture in center of each dough rectangle. Fold dough over filling and pressing edges together to seal.
Dip turnovers in remaining melted butter and then roll in breadcrumbs. Bake at 350 degrees for about 15-20 minutes or until golden brown. These can be assembled ahead of time and then placed in the oven 30 minutes before serving. If you find it difficult for the perforations to "hold together" you may want to try using a rolling pin to gently roll the perforations together.
