Set oven control to broil. Place chiles on broiler pan. Broil with tops 2 inches from heat, turning frequently, 6 to 8 minutes or until skins are blistered and lightly charred. Transfer chiles to resealable food-storage plastic bag; seal bag and place in bowl of ice water 5 to 10 minutes. Remove skin by running fingers down each chile. Cut stem and top off each chile. Cut slit down side, and remove seeds. Coarsely chop chiles; set aside.
Heat oven to 350°F. Spray bottom only of 13x9-inch (3-quart) glass baking dish with cooking spray.
In 10-inch skillet, cook sausage over medium-high heat about 7 minutes or until thoroughly browned, breaking into small pieces. Drain well; move to plate lined with paper towel. Pat with towel to remove additional grease.
Separate dough into total of 16 rounds. Cut each of 9 rounds into 4 pieces. Arrange pieces evenly in baking dish. Cut remaining 7 rounds in half for topping; set aside.
