Stromboli is a very versatile entree. Meats and cheeses can be of any combination to your liking. For example meatballs, mozzerella cheese, and hot pepper rings make a wonderful Stromboli. Italian sausage, roasted red and green peppers and onions are another delicious combination. Brushing top of dough will yield a nice golden crust. Cookie sheets are adequate for baking, a baking stone produces a finished product more like your local pizzaria.
