Sprinkle flour over the floor of the Dutch oven. Roll out the dough and spread it so that it covers the bottom of the Dutch oven.
Sprinkle the dough with olive oil, and place meatballs, vegetables and other toppings on top of half of the dough surface.
Pull the other half of the dough over the toppings, and use your fingers to seal the edges of the dough together to form a pocket.
Poke holes in the stromboli with a fork, allowing the pocket to vent.
Ignite the coals underneath the oven. For better effect, put some on top of the oven, for even cooking. Cooking should only take 15 minutes, and the results will be delicious.
