Preheat the oven to 350° F and cover a baking sheet with parchment paper. Mix together chicken, sauce, cheese, and seasonings in a large bowl. Gently roll out the crescent roll dough. Spread the meat mixture on the crescent roll dough, stopping ½ inch from the edge. Roll up the dough and meat mixture from one end to the other. Cut into one-inch–wide slices and place them on the baking sheet. Bake for 20 minutes or until golden brown and puffy. Garnish with green onions and serve with ranch dressing for dipping.
