Stromboli is everything delicious about pizza and a calzone combined. Rolled inside pillowy pizza dough, there’s a layer of tomatoes and a hearty spinach-mushroom filling. Cheese helps the filling and dough stick together, so don’t skimp on the mozzarella. Cooking the stromboli on a pizza stone ensures even browning on top and bottom of the dough. No pizza stone? No problem. Just assemble the stromboli on a parchment-lined baking sheet. If you have a favorite local pizzeria, sometimes they’ll sell you fresh dough. Make sure to ask for a one-pound ball, which is the amount you’ll need for this recipe.
