A stromboli is kind of a cross between a grinder and a calzone.
Bread dough is rolled out, filled with sliced meats, cheeses and
vegetables, then rolled up into a tube and baked.  To serve,
stromboli are simply sliced like a loaf of bread, creating a
spiral baked sandwich that is perfect for large parties. If you
like, you also can serve sandwich condiments (or even warmed
marinara) alongside the stromboli slices for dipping.  We've
offered suggestions for fillings; but mix and match to suit your
group (or devise your own combination).  Just be careful with
vegetables. Because you will be baking the fillings in the
dough, watery vegetables (such as tomatoes) can release too much
liquid during cooking. To avoid this, cook most vegetables in a
skillet before adding them. Sun-dried tomatoes would be a good
alternative to fresh.  Super BowlStromboli   Servings: 10  1
