You should use a pie iron that breaks down into two pieces. Spray non-stick cooking spray onto one half of the pie iron. Take two sections (making one square) of the raw croissant dough and cover the bottom of the pie iron. Add sauce and cheese (and any other topping) as desired. Lay pie iron on hot coals "open faced" for about 5 minutes. Dough will rise and cheese will melt making the perfect pie iron pizza!
