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 the 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. Ingredients 1 tablespoon olive oil 1 pound cremini mushrooms, sliced 1 small yellow onion, chopped 1 teaspoon kosher salt ½ teaspoon black pepper ½ teaspoon chopped fresh oregano 5 ounces baby spinach, roughly chopped 3 cloves garlic, chopped All-purpose flour, for work surface 1 pound prepared pizza dough, at room temperature 1 15.5-oz. can diced tomatoes, drained 6 ounces mozzarella cheese, shredded (about 1½ cups) 1 large egg, beaten Directions Preheat oven to 425°F with rack in lowest position.
